Nursing cat and kittens have fleas. What safe treatment can I use?

Updated on September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Female | unspayed | 5 lbs

Hi I have a momma cat and 2 10wk kittens. All have fleas. (Mom is a tiny little thing, kittens 1.5/1.7#) between the 3 I split one dose of catego (mom 1/2, kittens 1/4 ea). I separated mom so she couldn’t bathe them...THEN I see it’s not for nursing! Both kittens eat solid food 2x/d but can still be found nursing from mom...where do I go from here?!

Hello, thank you for using PetCoach.

Continue to keep the kitten separated from mom. They should have been weaned at 8 weeks of age anyway. They should definitely not be drinking her milk now. Keep them separated until her milk dries up. I strongly recommend you have her spayed as soon as possible before she becomes pregnant again.

You are also not dosing correctly. They should each be getting a whole tube. As long as they are at least 1.5 pounds in weight they should have a whole tube. If you are unsure of their weight you will need to weigh them. You can get a human baby scale or kitchen scale to weigh them.

All animals in the household should receive flea treatment EVERY month and you should also treat the environment for fleas; indoors and outdoors or you will continue to have problems.
