Hello there everyone my name is lori and my cat is tag. Well anyways my cat had her kittens by c section on the 25th of april. They have fleas, not too bad but I don't want to to get bad. She 7 kittens five of them survived. I need to know if the kittens are old enough to use flea stuff on tag. I have some revolution flea stuff is that okay? Also I'm new to this site so if I've posted in to wrong place again , my apologies. Than you for any help.
