My cat loves to chew on anything that is leather. He has ruined about 5 pairs of leather shoes and about 3 leather bags. he'll just chew and chew on it. My other cat loves to chew on paper. Its very strange.
One of them also likes to chase around q-tips. he won't eat it, other than to carry it...
My cat is 7 yrs old and generally a very quiet, content cat. Problem is.. when I'm not around, if someone goes anywhere near him he hisses his head off at that. If I'm there, he acts nice as can be and will never hiss. What's his deal??
