My cat got pregnant and had 4 kittens (she is getting fixed as soon as they are weaned) They all have fleas not a whole bunch but some. They were born on august 2nd so that makes them a little over 3 weeks old. i know flea treatments and shampoos are not good for them but What can i do? I know fleas are not safe. Can Mama Cat have a treatment and bath? Will it be safe for the kittens if so? Im not going to rush them to the vet though.
