That’s all you need to do to order your cat deworming and parasite medicine prescriptions from Chewy!

What is cat dewormer?

Dewormer treats roundworms, hookworms and whipworms by paralyzing and killing them, while tapeworms are killed and broken into smaller sections your cat can then pass. Some parasites, like hookworms and whipworms, are so small you may not see them in your cat’s stool at all. That is why you should visit your vet regularly and have her perform an exam and test your cat’s stool for parasites.

What prescription cat deworming and parasite medicine is best?

The best prescription deworming and parasite medicine for your feline will depend on which parasites or worms she has and what other problems you want to prevent or treat. Preventatives like Heartgard and Interceptor Plus protect against heartworm and treat and control intestinal worms, as well, while NexGard and Bravecto protect against fleas and ticks that can carry parasites. You can also buy standalone dewormers and targeted treatments for problems like mange, mites and ringworm. Ask your vet which products might be best for your cat.

Does cat dewormer cause diarrhea?

Dewormers can cause diarrhea and frequent defecation is a common side effect, too. The symptoms usually pass within a day or two and your kitty should be back to feeling normal by then, as well. Common side effects from dewormers include diarrhea, excessive salivation, vomiting or hair loss at the application site for topicals. Talk to your your vet if any side effects cause you concern.
