If you’re a cat owner, you may worry about worms affecting your pet. Worms are common in cats, and knowing what they look like can help you detect them early. Different types of worms have different appearances, and some may even be visible to the naked eye. In this article, we’ll explore the most common cat worms, their appearance, and how to identify them.
Common Types of Worms in Cats
Cats can get several types of worms, including:
- Roundworms
- Tapeworms
- Hookworms
- Whipworms
- Heartworms
Each of these worms looks different and affects cats in various ways. Let’s take a closer look at each one.
1. Roundworms
What Do Roundworms Look Like?
Roundworms are the most common intestinal parasites in cats. They look like spaghetti noodles—long, smooth, and white or light brown. Adult roundworms can grow up to 3-5 inches long.
How to Spot Them
You may see roundworms in your cat’s vomit or stool. Kittens often get them from their mother’s milk, while adult cats can get them from infected soil or prey.
2. Tapeworms
What Do Tapeworms Look Like?
Tapeworms are flat, segmented worms that can grow up to 8 inches or longer. The segments, called proglottids, look like small grains of rice or sesame seeds. These segments may break off and appear in your cat’s stool or around their rear end.
How to Spot Them
Tapeworm segments can sometimes be seen moving near your cat’s tail or in their litter box. Cats usually get tapeworms from fleas or eating infected rodents.
3. Hookworms
What Do Hookworms Look Like?
Hookworms are tiny—only about 1/8 inch long—and thin. They have hook-like mouthparts that latch onto the cat’s intestines. Because of their small size, they are hard to see with the naked eye.
How to Spot Them
Hookworms feed on blood, so symptoms like anemia, dark stools, or weakness may indicate an infection. Cats can get hookworms from contaminated soil or their mother’s milk.
4. Whipworms
What Do Whipworms Look Like?
Whipworms are thin, with a thicker front end and a long, whip-like tail. They are usually less than 1/4 inch long.
How to Spot Them
Whipworms are less common in cats than in dogs, but they can still cause diarrhea and weight loss. They are usually detected through a vet’s fecal exam.
5. Heartworms
What Do Heartworms Look Like?
Heartworms are long, thin worms that live in the heart and lungs. They can grow up to 12 inches long but are rarely seen because they stay inside the body.
How to Spot Them
Heartworm disease is serious and often shows no early signs. Coughing, lethargy, and difficulty breathing may appear in later stages. Mosquitoes transmit heartworms, so prevention is key.
How to Check for Worms in Cats
Visible Signs
Some worms, like roundworms and tapeworms, can be seen in:
Stool (look for moving segments or spaghetti-like strands)
Vomit (roundworms may appear here)
Around the tail (tapeworm segments may stick to fur)
Behavioral and Physical Symptoms
Even if you don’t see worms, your cat may show signs like:
Weight loss
Bloated belly
Diarrhea or bloody stool
Scratching or dragging their rear on the ground
Lethargy
Veterinary Diagnosis
A vet can confirm worms through:
Fecal tests (checks for worm eggs)
Blood tests (for heartworms)
Physical examination
How to Treat and Prevent Worms
Deworming Medications
Different worms require different treatments:
Roundworms, Hookworms, Whipworms – Oral dewormers like pyrantel pamoate
Tapeworms – Praziquantel is commonly used
Heartworms – Prevention is best; treatment is risky
Preventing Worm Infections
Regular deworming (especially for outdoor cats)
Flea control (since fleas carry tapeworms)
Clean litter boxes (prevents reinfection)
Avoid raw meat (can contain worm larvae)
Can Humans Get Worms from Cats?
Some cat worms, like roundworms and hookworms, can infect humans, especially children. To reduce risk:
Wash hands after handling cats or cleaning litter boxes
Keep cats on a deworming schedule
Avoid contact with cat feces
Conclusion
Worms are a common issue in cats, but knowing what they look like can help you take action quickly. Roundworms resemble spaghetti, tapeworms look like rice grains, and hookworms are tiny but dangerous. Regular vet check-ups, deworming, and good hygiene can keep your cat healthy. If you suspect worms, consult your vet for proper diagnosis and treatment. Early detection ensures your cat stays happy and worm-free!
By understanding the signs and types of worms, you can protect your feline friend and maintain a healthy home. Always stay proactive in your cat’s health care to prevent serious worm infections.
