So I've got good news and bad news. Got 10 weaned rats a few days ago, they've been doing great. Also got a few more mice for the breeding collection. None of which have tried any kind of chewing on the tubs.
However, today I started to hear a loud "thumping" from the tubs and I go to look...and it's the cat laying down trying to chew the zipties ever so delicately as to not catch my attention. When she sees me I get the "Oh $%!#!!" look from her and she bolts.
I swear, if it's not one it's another....no no, I take that back, it is usually the cat.
