Yes, deworming is necessary for cats. Many kittens have intestinal parasites, and if they aren't dewormed when they're young, they can harbor these parasites into adulthood. It's essential to talk to your veterinarian about deworming your cat to ensure their long-term health.

Kittens should be dewormed multiple times throughout their early development due to the intermittent egg-laying and life cycles of parasites. As for adult cats, the deworming frequency depends on their lifestyle. Most cats will be dewormed once or twice during their adult life to keep them parasite-free.

While there are some over-the-counter deworming products available, it's essential to know which parasite you're treating before administering any medication. Most kittens have roundworms and hookworms, but it's recommended to consult with your veterinarian or have them prescribe the dewormer. This ensures the correct dosage based on your cat's size and specific needs.

There are several deworming medications available, and the specific medication used depends on the parasite that needs to be treated. After discussing with your veterinarian and identifying the parasite, they will recommend the best deworming medication for your pet.

Your cat is tested for worms with a fecal material sample. You'll need to collect some fresh fecal material from the litter box. Having a little litter on the sample is okay, and you usually need about a teaspoon-sized amount. The test will help identify the type of parasite your cat might have.
