How to safely deworm a pregnant cat with worms before she gives birth?

Updated On September 23rd, 2025

Pet's info: Cat | Persian | Female | unspayed | 10 months and 14 days old | 3 lbs

My cat Minhu (she is 11 months old ) she is pregnant with her first litter. I was deworming her before pregnancy and i found out abt her pregnancy so i stopped. She has worms and its been 2 month since she has worms and i didnt deworm bcx of pregnancy. Now she is abt to deliver her first litter in 6,7 days. Can I give her Vermox (oral suspension) or Praferan Dewormer to prevent her newborn from worms ? and i dont have Drontal Nor Panacur .

Unfortunately, neither of those options might be safe. We do not have very many safe deworming medications for pregnant animals. The active ingredient in Vermox is Mebenzazole which is considered FDA Pregnancy category C which means that animal reproduction studies have shown an adverse effect on the fetus. The active ingredients in Praferan are Pyrantel, Febendal and Praziquantel. We do not have this product in the US available for cats. It is only available for dogs and is listed as NOT being recommended in pregnant dogs. The type of deworming medication recommended really depends on the type of worms that are present, so I think the safest option would be to ask your veterinarian for a recommendation for Minhu and the kittens once they are born. Good luck! Thanks for using Petco Pet Education Center, formerly Petcoach.
