rabbits', guinea pigs', and chinchillas' teeth are the same way. it's 1 of the reasons why they need a supply of hay.
i don't know if hamsters', chipmunks', squirrels', mice's, rats', etc. teeth are that way.
Squirrels chew on power lines to wear theirs down.
Don't rats have "selfe sharpening" teeth? so that no matter where they chew through - be it even a metal pipe - their teeth never wear down.
