i have 3 cats. The newest kitten has been with us a little over a month and brought fleas. i really dont have the money for the expensive flea treatment and my biggest concern is all of the cats are constantly grooming each other. so i have the fear of getting the good flea treatment and having one of them lick it and get very sick. i cant stand seeing them suffer like this and i did some searches but cant come up with much...bathing the 2 older cats would probably be hell. can anyone put me in the right direction? thank you!
