Whipworm is a type of intestinal parasite that can infect cats. The scientific name for whipworm is Trichuris. These worms live in the large intestine and cecum (a part of the digestive system). Whipworm infections are less common in cats than in dogs, but they can still cause health problems.
Cats get whipworm by swallowing eggs from contaminated soil, water, or feces. The eggs hatch inside the cat’s body and grow into adult worms. These worms attach to the intestinal wall and feed on blood, which can lead to diarrhea, weight loss, and anemia.
How Cats Get Whipworm
Whipworm eggs are passed in the feces of infected animals. These eggs can survive in the environment for months or even years. Cats can pick up whipworm by:
Eating contaminated soil or grass – Cats that go outdoors may accidentally swallow whipworm eggs while grooming or exploring.
Drinking contaminated water – Puddles or stagnant water may contain whipworm eggs.
Contact with infected feces – Cats that share litter boxes with infected cats are at risk.
Once inside the cat’s body, the eggs hatch and develop into adult worms in about 70 to 90 days.
Symptoms of Whipworm in Cats
Not all infected cats show symptoms. Some cats carry whipworm without any signs. However, severe infections can cause:
Chronic diarrhea – Often with mucus or blood
Weight loss – Due to poor nutrient absorption
Lethargy – The cat may seem tired or weak
Dehydration – From prolonged diarrhea
Anemia – Pale gums due to blood loss from the worms
If your cat has these symptoms, a vet visit is necessary.
Diagnosing Whipworm in Cats
Vets diagnose whipworm by checking a cat’s stool sample. Whipworm eggs are shed intermittently, so a single test may not detect them. Multiple stool tests may be needed.
Common Diagnostic Methods:
Fecal Floatation Test – A stool sample is mixed with a special solution that makes worm eggs float to the top. The eggs are then examined under a microscope.
PCR Test – A more advanced test that detects whipworm DNA in the stool.
Blood Tests – May be done if anemia is suspected.
If whipworm is confirmed, treatment should start immediately.
Treatment Options for Whipworm in Cats
Treating whipworm requires deworming medication and good hygiene practices.
1. Deworming Medications
Not all cat dewormers kill whipworms. Common medications that work include:
Fenbendazole (Panacur®) – Given daily for 3 to 5 days.
Milbemycin Oxime (Interceptor®) – A monthly heartworm preventative that also treats whipworm.
Moxidectin + Imidacloprid (Advantage Multi®) – A topical treatment that helps control whipworm.
Your vet will choose the best option based on your cat’s health.
2. Supportive Care
If the cat is dehydrated or anemic, additional treatments may include:
Fluid Therapy – Given under the skin or intravenously.
Iron Supplements – For cats with anemia.
Probiotics – To help restore gut health after diarrhea.
3. Environmental Cleaning
Whipworm eggs are tough and can survive in the environment. To prevent reinfection:
Clean the litter box daily – Use hot water and disinfectant.
Wash bedding and toys – Use bleach or pet-safe cleaners.
Keep outdoor areas clean – Remove feces from the yard promptly.
Preventing Whipworm Infections
Prevention is better than cure. Here’s how to protect your cat:
1. Regular Deworming
- Use a monthly parasite prevention product that covers whipworms.
- Follow your vet’s deworming schedule.
2. Hygiene Practices
- Wash hands after handling cat litter.
- Keep litter boxes clean.
- Avoid letting cats drink from puddles.
3. Limit Outdoor Exposure
- Supervise outdoor time to prevent eating contaminated soil.
- Keep cats indoors if whipworm is common in your area.
Can Humans Get Whipworm from Cats?
The whipworm species that infect cats (Trichuris serrata) rarely infect humans. However, good hygiene is still important. Always wash hands after handling pets or cleaning litter boxes.
When to See a Vet
If your cat has:
- Bloody diarrhea
- Severe weight loss
- Lethargy lasting more than a day
Take them to the vet immediately. Early treatment prevents complications.
Conclusion
Whipworm infections in cats are treatable with the right medication and care. Regular deworming and good hygiene can prevent reinfection. If you suspect your cat has whipworm, consult a vet for proper diagnosis and treatment. By following these steps, you can keep your cat healthy and worm-free!
