My kitten has roundworms. Dewormed today. Is it working? Am I at risk?

Updated on September 23rd, 2025

Pet's info: Cat | American Shorthair | Male | unneutered | 1lb

I have a six week old kitten who has roundworm. He got dewormed today plus a dose of Revolution given by the vet. I have to help him clean up after using the litter box and today I pulled out a roundworm, man did it freak me out! I dropped it, horrifed, and noticed it didnt move. Did the dewormer already take affect? Am I still at risk if he sleeps on my bed? Thanks!

Hello. As the dewormer works (and yes it is that fast) the worms that were inside your kitten will be passed out in the poop. This may continue to happen for the next few days. Make sure you follow the deworming protocol that your vet has suggested as the various stages of the worms need to be killed at different times, so a one-time shot won't necessarily work depending on the product. Also, roundworms can be contracted by people, and the eggs are shed through the feces, so if you are 'eating' (fecal bits on your pillow and your face goes on this) the feces then you could get the worms. The shedding period will last until the burden is gone, so I would give it a couple months. It would be very unlikely for you to contract worms through this method however. Good luck with Newt!

    Oh no, poor Newt! Yes you can get roundworms from her, but also long as you wash your hands thoroughly after every time you touch her, clean up her diarrhea completely, and wash your hands after you clean up, you should be fine :-)
