Cats can get parasites. It happens often. Both indoor and outdoor cats face this risk. Parasites live on or inside your cat. They feed off your pet. This can cause health problems.
Some parasites are tiny. You can’t see them. Others are big enough to spot. All parasites harm your cat in some way. They steal nutrients. They cause discomfort. Some spread diseases.
As a cat owner, you should know the signs. Early detection helps. Treatment works better when started early. This guide explains everything about cat parasites.
Common Types of Cat Parasites
External Parasites (Live on the Outside)
Fleas are common. They jump on your cat. Fleas bite and suck blood. You might see tiny black dots. These are flea dirt (poop). Fleas cause itching and scratching.
Ticks attach to skin. They swell with blood. Ticks look like small bumps. Check your cat’s head, neck and ears. Ticks carry diseases.
Ear mites live in ear canals. They cause black, crusty discharge. Your cat will shake its head. It may scratch its ears a lot.
Internal Parasites (Live Inside the Body)
Roundworms are common in kittens. They look like spaghetti. You might see them in vomit or poop. They cause potbellies in kittens.
Tapeworms come from fleas. Segments break off. These look like rice grains. You’ll see them near your cat’s bottom.
Hookworms suck blood. They cause anemia. Stools may look dark or bloody. Cats get them from contaminated soil.
Heartworms are serious. Mosquitoes spread them. They live in heart and lungs. Coughing and tiredness are signs.
How Cats Get Parasites
Cats get parasites in different ways:
- Eating infected prey (mice, birds)
- Walking on contaminated soil
- From mother cat to kittens
- Contact with other infected animals
- Flea bites (for tapeworms)
- Mosquito bites (for heartworms)
- Sharing litter boxes or food bowls
Outdoor cats face higher risks. But indoor cats aren’t safe either. Fleas can come inside on clothes. Mosquitoes get indoors too.
Signs Your Cat Has Parasites
Watch for these warning signs:
Physical Signs
- Visible worms in poop or vomit
- White specks in fur (tapeworm segments)
- Black dirt in coat (flea dirt)
- Pale gums (sign of anemia)
- Potbelly in kittens
- Dull, rough coat

Behavior Changes

- Lethargy or weakness
- Coughing (heartworms)

Diagnosing Parasites in Cats
Home Checks
Check your cat regularly:
Fur check: Part the fur. Look for fleas or dirt. Use a flea comb. White paper helps spot flea dirt.
Ear check: Look inside ears. Healthy ears are pink and clean. Dark wax means mites.
Bottom check: Look for tapeworm segments. They move when fresh.
Litter box check: Look at stool. Note any changes.
Vet Visits
Take your cat to the vet if you see signs. The vet will:
- Ask about symptoms and history
- Do a physical exam
- Check a stool sample (fecal test)
- Possibly do blood tests
- Examine skin scrapings if needed
Fecal tests find many parasites. But they’re not perfect. Some parasites don’t show up every time. Multiple tests may be needed.
Treating Cat Parasites
Treatment depends on the parasite:
Fleas
- Flea medication (topical or oral)
- Flea shampoo or dips
- Treat your home too (vacuum, wash bedding)
Ticks
- Remove ticks carefully with tweezers
- Use tick prevention medication
- Check for tick diseases
Ear Mites
- Ear drops or ointments
- Clean ears first
- Treat all pets in home
Intestinal Worms
- Deworming medications
- Different drugs for different worms
- Multiple doses often needed
- Treat all household pets
Heartworms
- Prevention is best (monthly medication)
- Treatment is risky and expensive
- Requires vet supervision
Never use dog parasite medicine on cats. Some are toxic to cats. Always follow vet instructions.
Preventing Parasites in Cats
Prevention works better than treatment:
Monthly preventatives: Many products cover multiple parasites. Ask your vet.
Clean environment: Wash bedding. Vacuum often. Keep litter boxes clean.
Limit hunting: Indoor cats get fewer parasites. Use toys to satisfy hunting instinct.
Regular vet checks: Yearly exams catch problems early. Bring stool samples.
Grooming: Brush your cat often. Check for fleas and ticks.
Proper nutrition: A healthy cat fights parasites better.
Quarantine new pets: Keep them separate at first. Check for parasites.
