I found that my cat had worms yesterday. I purchased a dewormer called Pro-Sense. The cat is in the bathroom because he keeps dropping worms everywhere. Is this normal and how long should it last? I gave it to him at 6 pm

Hello. Dallas may have tapeworms. This can be confirmed by your veterinarian if you submit a stool sample or segments of the worms for examination. The dewormer you used does not take care of them. You will need a medication that has either [Panacur]() (fenbendazole) or [Drontal for Cats]() (praziquantel)to eliminate tapeworms. Tractor Supply, Petco & other major pet retailers should carry these products for cats. Just follow all label directions. If tapeworms are diagnosed, you will also need to treat Dallas and his environment for fleas since that is how tapeworms are spread. Thanks for using PetCoach.
