Worms are a common problem in cats. They can cause serious health issues if left untreated. As a cat owner, it’s important to know how to identify, treat, and prevent worm infections. This guide will cover everything you need to know about deworming medications, natural remedies, and preventive measures.
Cats can get different types of worms, including roundworms, tapeworms, hookworms, and heartworms. Each type requires a specific treatment. Some worms are easy to spot, while others may not show obvious signs. Regular vet check-ups and proper medication can keep your cat healthy and worm-free.
Common Types of Worms in Cats
1. Roundworms
Roundworms are the most common intestinal parasites in cats. They look like spaghetti and can grow up to several inches long. Kittens often get them from their mother’s milk. Adult cats can get them by eating infected rodents or soil.
Signs of roundworms:
- Bloated belly
- Diarrhea
- Vomiting (sometimes with worms visible)
- Weight loss
2. Tapeworms
Tapeworms are long, flat worms that attach to a cat’s intestines. Cats usually get them by swallowing fleas that carry tapeworm eggs.
Signs of tapeworms:
- Rice-like segments near the cat’s tail or in feces
- Excessive licking of the anal area
- Weight loss despite eating normally
3. Hookworms
Hookworms are small but dangerous. They attach to the intestinal wall and feed on blood. Cats can get them through skin contact or by eating contaminated soil.
Signs of hookworms:
- Pale gums (sign of anemia)
- Bloody diarrhea
- Weakness and lethargy
4. Heartworms
Heartworms are spread by mosquitoes. They live in the heart and lungs, causing severe damage. Unlike dogs, cats are not natural hosts, but infections can still be deadly.
Signs of heartworms:
- Coughing
- Difficulty breathing
- Sudden collapse (in severe cases)
Symptoms of Worm Infestations in Cats
Not all cats show obvious signs of worms. Some may appear healthy but still have parasites. Here are common symptoms to watch for:
Visible worms in feces or vomit – Some worms, like roundworms and tapeworms, can be seen with the naked eye.
Weight loss – Worms steal nutrients, causing cats to lose weight even if they eat well.
Diarrhea or bloody stool – Intestinal worms irritate the digestive system.
Vomiting – Some cats vomit worms, especially roundworms.
Dull coat – A healthy cat has a shiny coat. Worms can make fur look rough and unkempt.
Lethargy – Infected cats may seem tired and less active.
If you notice any of these signs, take your cat to the vet for testing.

There are many effective deworming medications available. Some treat specific worms, while others are broad-spectrum (work against multiple types).

Topical treatments: Apply to the skin where the cat can’t lick it off.
Always follow the vet’s instructions for dosage and frequency.
Natural Ways to Prevent and Treat Worms
While medications are the most effective treatment, some natural remedies can help prevent worms.
1. Pumpkin Seeds
- Contain an amino acid that paralyzes worms.
- Grind seeds and mix with food (1/4 tsp per 10 lbs of body weight).
2. Diatomaceous Earth (Food Grade)
- A fine powder that dehydrates worms.
- Mix a small amount into your cat’s food (consult a vet first).
3. Probiotics
- Support gut health and make it harder for worms to thrive.
- Found in yogurt (plain, unsweetened) or probiotic supplements.
4. Garlic (In Small Amounts)
- Has natural anti-parasitic properties.
- Use only in tiny doses—too much can be toxic.
Note: Natural remedies should not replace vet-prescribed medication for severe infections.
How to Prevent Future Worm Infections
Prevention is easier than treatment. Here’s how to keep worms away:
1. Regular Deworming
Kittens should be dewormed every 2 weeks until 3 months old.
Adult cats should be treated every 3-6 months.
2. Flea Control
Fleas carry tapeworms. Use flea preventatives like Frontline or Advantage.
3. Clean Litter Boxes
Scoop daily and disinfect weekly to kill worm eggs.
4. Keep Cats Indoors
Outdoor cats are more likely to eat infected rodents or soil.
5. Avoid Raw Meat
Raw meat can contain worm larvae. Cook meat thoroughly if feeding homemade diets.
6. Regular Vet Check-ups
Fecal tests can detect worms before symptoms appear.
Conclusion
Worm infections are common but manageable with the right medication and care. If your cat shows signs of worms, visit the vet for proper diagnosis and treatment. Deworming medications like pyrantel, praziquantel, and selamectin are highly effective.
Natural remedies can help but should not replace prescribed treatments. Prevention is key—regular deworming, flea control, and good hygiene will keep your cat healthy.
By staying informed and proactive, you can protect your cat from the discomfort and dangers of worms. Always consult your vet before starting any new treatment.
A worm-free cat is a happy, healthy cat!
