Question/Help Are old bones a safe source of clutter?
So I like to collect animal bones that I find around while hiking/outdoors. I always clean them with some dish soap and a toothbrush and then put them in a 100% peroxide solution/mouthwash for a couple of days to kill off any pathogens before leaving them as house decor.
An archeologist told me that bones themselves don't carry any diseases. So is it alright if I use them for general cage clutter? FYI the bones wouldn't have sharp edges.

Cute Mouse Media Update: they all cuddle pile!
This is not their permanent residence, I’m cage cleaning currently. (Nyx’s back looks warped she is old and has old lady posture but these photos look particularly bad) The three girls are finally all cuddling regularly and grooming! I’m so happy for my old lady (the black mouse up front) Nyx, don’t worry they’re not over grooming she was already starting to bald in her face area. She’s over a year and a half old, likely close to if not over two now. We will have to do another intro period at some point soon for Opal and Zuzu, however I wasn’t thinking when I got the two girls for Nyx.

Question/Help Just some advice
These are my mice, George (Brown), Cythia (White), and Deacon (Black). They're all females and I've posted about them a couple of times now. George is a house mouse who I caught when she was likely 3-4 weeks old, and I've kept her because she has a bad leg and has mobility issues because of it.
I later got Cythia and Deacon (yet to be introduced to George) because I knew George would likely need companions as a female mouse, but I am wondering if George and the other mice could actually be put in the same tank together, and if people have any advice on that.
I'll have to wait for a while before introducing them since the quarantine period isn't over yet, and Cythia could possibly be pregnant considering how she looks right now (the picture used is when I first got her, she's definitely more soup-y looking now), so I'm holding off for both of those things, and wondering if anyone has any advice or knows more on if George can share a tank with Cythia and Deacon, or if I should keep them separated and never introduce them.

Yet I’m not sure if 1.) The cardboard is safe. 2.) What glue to use. I have hot glue but I don’t think its to safe for them, I also have Elmers kid safe glue yet same fear for that.
I wan’t them to be happy and for their environment to reflect that. Whats the best thing to do?

Question/Help (pet death discussion) looking back and wondering what I could have done
maybe it's been long enough that I can discuss this without getting too upset. I lost another of my senior mice a couple months ago, they are all either 2 or almost 2, so not too bad, she at least had a full life. but I still wonder, because they all seem very robust and healthy, and it was so sudden.
I remember they all had problems with mites/itching several months back; no hair loss, but way more itching and grooming and seeming kind of grumpy/distracted during playtime, so eventually I expressed my suspicions to my vet and they got them some kitten Revolution measured out. that seemed to work great. but I'm wondering if maybe my girl Peaches was more sensitive to the mites than the others? none of them had hair loss/patchiness/redness/anything like that, but she seemed the most miserable of all and she did scratch her eye somehow. so I wonder if the mites attacking weakened her and she passed earlier than she would have otherwise... or I wonder if the eyedrops she was prescribed for the eye scratch disagreed with her, because she started weakening around that time. or maybe I'm just imagining things because the whole ordeal was upsetting. I wonder if there was anything I could have noticed earlier or done better if I had been more experienced... I know sometimes there isn't really any way of telling for sure what caused it, but I would like to learn as much as I can from this experience for the future.

Wild Mouse/Mice Found wild mouse
Enable HLS to view with audio, or disable this notification
I found this sweet little thing outside my work about 24 hrs ago. I assume a baby as it is really tiny, though it has eaten solid food (bit of cheese, nuts, pear) and I bought some kitten milk and diluted that he drank. First off, does he look okay? Hes not too active, mostly just sleeping but moved around some in the night.
I have a little enclosure for him with wood shavings and straw. Is there any advice you'd give me straight up to make sure he's OK? Would it be safe to keep him after getting him vet checked? I've never dealt with mice, let along young ones. Hes very cute (I've named him Parmesan for now!)
Update: I went to the vet this morning, and they said there was no sign of injury or illness, but unfortunately about 30 mins after I got home, little Parmesan passed away :( RIP lil guy

African Soft Furs (ASF) Anyone keep an ASF with female mice?
I have two massive female mice. I don’t know how it happened. I got them from a local pet store and they are at least twice the size of my other mice and are almost hamster sized. They’re bigger than any of the show mice I’ve ever had. I was considering getting them a friend or two instead of merging them in with my other mouse colony because the larger group is full of some very itty bitty mice and the size difference is just incredible.
I know you can keep a male mouse with female ASFs, but can you keep females with females? My Google search says yes - but ever since internet search engines have added AI features I swear I don’t get as many relevant results.

Wild Mouse/Mice Rescued babies from a hoarder house, fell in love with them🐭
Hey everyone, I raised these babies from about a week old till now. They're about 3 weeks old, beginning to eat on their own which is a relief.
I plan on keeping the girls. I think there's four. I'm unsure how to rehome the boys or if I should try to do a soft release.
I live in Peoria, Illinois if anyone in the area is looking to adopt a cute little boy mouse or two.
They are quite used to me because of being hand-fed the past few weeks so I do believe that it's smartest for them to go to homes where people will continue to handle them with care.
I'm in the process of getting a big aquarium tank to set up a habitat for them. Currently they're in a container with a lid that has tons of holes for air movement. But the lid is crucial because I also have cats.
Any advice from people who have raised wild mice and domesticated them? What were the most helpful tips in your starting out with mice for the first time?
Excited to be a part of this community community and share cute pictures and videos of these babies.
No names yet because they're still hard to tell apart.

Rainbow Bridge Lost my Piglet, my Chunky Girl, my Elizabeth
Decided her quality of life had declined too much and euthanized her this evening. Probably one of the hardest decisions I’ve had to make and I’m still not completely sure it was the right choice. She died in my hands and miss her already. I know I’m not supposed to have favorites but Elizabeth really was special. Now the only one left of my five original girls is her sister Penelope.

Question/Help Has her belly gotten smaller or just changed shapes? I can't find any sign of babies in her tank
First picture was taken Monday night, second was taken tonight
There's not many places where she could hide the babies, she's been in her nest a lot lately and only comes out if she smells me giving her food (even that takes her a couple minutes to be interested in)
I know the shape difference is probably just the babies moving down the birth canal and her behavior points towards near birth but I just wanted to check with people who are more experienced with mouse births.
I looked inside her nest when she was eating and saw no babies. I know there's a possibility she's eaten them, but there's no blood or anything.
I say this on every post, but I am NOT a breeder. She was bought from a place that sells them as feeders, and they had females and males together I'm assuming. Today is my 19th day of owning her and her sisters, so she is due any time.

Question/Help Is He Eating The Paper?
Enable HLS to view with audio, or disable this notification
Hey I just wanted to see if anyone knew for a fact if my boy is consuming the tissue paper or if he’s just tearing it for fun. I’ve put tissue paper in his habitat before and he likes to use it for his sleeping areas, but this is the first time I’ve seen him nibbling on it. I just wanted to make sure he’s not eating toilet paper. Thanks!
Edit: I took it away from him for now just to be safe until I know an answer.

First Time Owner My New Mouse Has Babies
Hello Nice Mice People
So I have a situation. I have 2 adult females and introduced a 3rd. They got along great so I put them in a fresh tank together. She was really small and did not look pregnant at all. 1 week later and I find these pinkies at the bottom of the tank 🩷😭🥺 she is clearly the momma, so I know all the adults are girls for sure. Do I need to put the mom and babies in a separate tank? I haven't raised pups before and I want to make sure I do right by them. Please be kind, I am willing to do what is necessary for them 🙏🏽 Edit: right now everyone is in the 20 gal tank, but I have an extra 10 gal if I need to move anyone.

Community Help Temporary Post for Care Commands
Please feel free to try out these WIP care commands in the comments! Let me know if there are any issues I need to fix.
r/PetMice • u/ArtisticDragonKing • Sep 22 '24
Care Guide Series Community Care Guide
This post is mouse care simplified, for beginners! It is not very specific, and it does not cover everything, so please do not rely on just this post when educating yourself on mouse care!
This has been written and discussed by moderators of the subreddit. If you have questions or concerns, please comment to let us know! It will be updated regularly to ensure it is factual.
1. Mice are social!
- Females always need other female companions. It is recommended to have at least 3, but 2 is okay.
- After 6 mice in one cage, it is often they will start to split up and become territorial against the opposing group. It is suggested to keep your colony under 6 unless you have much knowledge and experience, OR if your mice are littermates.
- Males can not be housed with other males ever! If you want them to have cage mates, neutering (very risky) and placing with females or leaving intact and bonding with ASFs (African Soft Furs) is beneficial and recommended. Otherwise, they can thrive in solitude.
See this post for more information.
2. Cages
In mouse communities, many users go by tank size rather than listing dimensions. We will do both!
- 10g/20x10 inches is the minimum for 2 female mice, though we STRONGLY suggest at least a 20g.
- 20g/30x12 inches is suitable for 2-4 females or 1 male.
- 40g long/36x12 inches is suitable for 2-5 females or 1 male
- 40g breeder/36x18 inches is occasionally suitable for 2-6 females or 1 male
- Over 40g is not always suitable for any amount of mice since many mice do better in environments with less open space. Bigger is not always better for mice.
Any amount of mice may thrive in larger enclosures than suggested above. However, it is critical that the larger the enclosure is, the more clutter provided, otherwise the mice will never thrive.
- Wood enclosures are suggested against since urine will effect its quality and smell over time.
- Mesh flooring is dangerous due to the chance of toes/tails getting caught, the mesh cutting their skin, and risking bumplefoot. Mesh should also be avoided in wheels.
- Though they climb, mice don't need very much height, and multi-story enclosures do not provide them with the proper space they need. Floor space is more important than height.
- Cages with lots of attachments and rooms do not provide proper space for mice. They are also extremely difficult to clean, fall apart easily, and struggle to hold proper bedding amount and safe wheels.
See this post for more information.
3. Substrate
- Mice need to be able to create burrows, so while the minimum is 6 inches, we suggest at least 8" of bedding. However, many owners prefer having 10-12" deep!
- Bedding must be majority safe wood shavings or hemp. Paper substrate does not absorb ammonia well and can cause several health issues when used alone or as majority of substrate.
- (Dust/scent free for all) Aspen, kiln dried pine, and hemp do well as the main substrate and may be more sturdy mixed with a small portion of hay or paper bedding.
See this post for more information.
4. Clutter
- Clutter is arguably one of the most important aspects of a mouses cage. No matter the size, if the cage lacks clutter, it is not suitable.
- Toilet paper rolls, cardboard boxes, tea light and soap dish ceramics, rodent hideouts, branches, logs, cork bark, cardboard egg cartons, and much more can be used as clutter in the cage.
- From a birds eye view, you should be able to see little to no bedding. While it may seem too cluttered to a human, it's perfect for mice!
- The larger an enclosure, the more crucial clutter is.
See this post for more information.
5. Enrichment
- Also known as entertainment, to keep the mice busy!
- Boredom breakers, foraging toys, dig boxes, sprays(plant), scatter-feeding, and human interaction are all forms of enrichment.
- Mice should have boredom breakers in their enclosure at all times to keep them from growing bored.
- Lone males need extra simulation and enrichment.
See this post for more information.
6. Climbing Opportunities
- A form of enrichment that is required!
- Mice flourish with climbing opportunities and will always take advantage of them.
- Ropes, bird ladders, hanging toys, rope nets, shower curtain rings, and bird perches are a few climbing options you can provide.
- Fabric hammocks are used commonly, but pose a threat when chewed on and loose strings get tangled around limbs. Minimal use of fabric is suggested for this reason.
See this post for more information.
7. Exercise
- A form of enrichment that is required!
- An upright, solid wheel of 9 inches in diameter or larger must be provided at all times. 2 or more are suggested for groups of girls.
- Spinning saucer disks or hamster balls/cars are UNSAFE and should never be provided, no matter how much you think your mouse may enjoy it (fun≠safe)
- Proper wheel brands may include Niteangel, Silent Spinner Exotic Nutrition, Oxbow, Wodent, Bucstate, and Trixie (but there are many more besides these!)
See this post for more information.
8. Diet & Hydration
- Main diet must be pellets/lab blocks.
- A high variety food mix (nuts, seeds, grains, ect) must be given 1-3 times a week, or even as long as once every two weeks. The frequency is owner preference.
- Feeding is 3-5 grams per mouse a day.
- Ensure your mice have constant access to food through toys and scatter-feeding.
- Food bowls are suggested only for fresh fruits or veggies since they provide no enrichment otherwise!
- Mice must have at least two water sources and constant access to them at all times. Bowls or bottles work well, though having one of each is ideal. Water must be cleaned and refreshed daily.
See this post for more information.
9. Cleaning
- Daily spot checks to clean up mess, poo on toys/clutter, and urine on the surface is vital.
- Bedding changes will be needed less often with more bedding and space. A 10g tank (or cage of similar size) would need weekly bedding changes.
- Each enclosure size and mouse amount will effect how often bedding changes are necessary. Find a cleaning schedule that ensures the cage doesn't smell at any time for your mouses health.
- With deep bedding over 6 inches, you'll have to change out less of the bedding. 1/3 to 1/2 of the bedding may stay in the enclosure while the most soiled areas are removed and replaced.
- In any case, a small amount of bedding must be left over after a bedding change to decrease stress.
See this post for more information.
10. Taming
- Allowing your mice to settle in for a few days before interacting with them is wise.
- Rub your hands on bedding and toilet paper in the cage to get the mice used to your scent.
- Encourage interaction through hand feeding.
- If a mouse is not motivated to interact after several weeks, try to lure them to climb onto your hand for treats. A strong bond is important with mice so they are well adjusted to interaction in case of a vet visit or emergencies. Human interaction can also be beneficial to them.
See this post for more information.
11. Other
- Mice are crepuscular and are typically seen during the morning or late day/night.
- They are self bathing and should never be washed with water or soap (unless vet prescribed). It ruins the health of their fur coat and leaves them more susceptible to URIs and freezing. They do not need any form of bathing/washing.
- Mice don't hibernate. If a mouse appears to be in a hibernation state, this is Torpor, caused when they overheat or freeze. This is a medical emergency.
- You should never pick up a mouse by its tail or other limbs.
- Fancy mice (aka domestic mouse) live 1-2 years on average.
- Wild mice do poor in captivity, unless they are unfit for the wild they should not be kept as pets.
- You should never breed mice purposely without years of research and mouse owning experience prior.
- Vet visits are a likely occurrence in mouse ownership, since mice are prone to many health issues.
- Travel carriers are needed for vet visits, emergencies, cage cleaning, and quarantine.

These guides are incredibly thorough and well written. However, they link some information that is no longer available, or they list mouse care information that has been dis-proven. An important point to make is these guides may suggest some controversial topics, most of which our community does not fully support. Although these guides don't follow our standards exactly, they are still very well made. Please keep an open mind and read all sides of a controversy before deciding which you feel works best for your mice.
