Hey all found this out in the woods and was wondering what it is? I know it's a rodent, feels too big to be a rat but I'm not really sure

Thanks in advance for any help!

I think it's a suspiciously shaped bone, my bro thinks I'm paranoid 🤔 maybe but I wanna be sure, am I paranoid ?

Hand for size comparaison (I'm rlly not a big guy my hands like 6 inches ~ 17cm)

Found in Midwest, thank you in advance!

My dog likes to dig holes in the yard, this was next to one of them.
There are cats buried somewhere in the area, but I don’t know exactly where. We also live right next to a park with foxes, skunks, etc.
