Yup.I know, our worst problem with chewed wiring around here seems to be with squirrels. I'd have never dreamed that untill after doing several chewed wire repairs and talking to customers several of em reported watching squirrels run in and out from under their cars the same day they had to have em towed in. But it is a common fo us to find nests from mice or chipmunks in air cleaners and heater blower squirrel cages.
