Safe to worm nursing cat and her kittens? When to flea treat them?

Updated on September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | 1lb

Is it safe to administer Pyrantel Pamoate and Praziquantel to a lactaing mother cat? And how old must the kittens be before I can worm them? Also what age is it safe to give a flea treatment to the kittens?

I usually do not recommend using Praziquantel in lactating mother cats, Pyrantel Pamoate is usually fine and they can be dewormed from around 4 weeks of age. flea treatment can be given as soon as 2 days of age-- the ONLY safe product is Frontline spray.

    All nursing moms should have at least 2 doses of dewormer 2-3 weeks apart. Worms are passed to kittens while nursing so it is highly likely that all the kittens have worms. The standard recommendation is to deworm all kittens at weeks 2, 4, 6, and 8 with pyrantel pamoate and make sure momma cat is treated as well.
