my cat used to steal cigarrete butts amd chew on them. that was a while back. could that have caused any harm? i almost always caught him before chewing it but other times he had done it already. it was those roll your own cigarretes kinda thing so i it didnt have any tobacco but idk what the filter is made of. also when i make scampi shrimp he likes to lick and chew on the shrimps tail and i do use garlic to make it... is it bad if he just licked the tails?
