They eat pens, pencils, carpet fibers, and my pants! ! They normally do this at night when everyone is sleeping. They are crated during the day, and get alot of playtime, and excercise at night. I dont want to have to crate them again at night...what can I do? Oh and they hate those rubber chew toys, they only ones they enjoy are the stuffed animal ones that they destroy in about 10 minutes. What can I do for my babies?
