Mice, Rats, Squirrels, Rabbets, Beavers, Ground Hogs and many other critters are all part of the rodent family.
If they don't chew on something there teeth will continue to grow.
Some such as the Rabbet chew a cud like a cow.
As far as I'm concerned they are all tasty if you go without food for about 3 days.
I had rather eat a big rat than eat a nasty old alligator.
