Many deworming products are not recommended once pregnancy is established. Tapeworm medications, in particular, can be quite toxic. If you are concerned that your cat has parasites, I recommend that you take a fecal sample to your veterinarian for examination. Your vet can identify the eggs of any parasites your cat may have using a test called a fecal float exam. S/he can then prescribe the safest, most effective dewormer to use in a pregnant cat for that particular parasite.

    Praziquantel, the medication most commonly used to treat tapeworms, is safe to use during pregnancy. I would however recommend consulting a veterinarian before giving any drugs to Stashie to make sure she is healthy enough for the medication. Tapeworms are most commonly transmitted through fleas, so you may want to inspect her for fleas as well.

    Great question! Drontal is an excellent deworming treatment, and it's safe to use in pregnant cats. You will need to get it from your vet, however, as it's a prescription medication. I hope this helps!

    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.
