Your cat is the queen of naps and nose boops… but worms? No, thank you. Here’s your clear, gentle, and totally doable plan to protect your cat from pesky parasites—without turning your home into a lab. Ready to keep that tummy purr-happy?
The types of worms cats can catch
Roundworms
These spaghetti-like freeloaders love the intestines. Kittens can pick them up from mum, and adults can get them from contaminated soil or prey. The larvae migrate through the body before settling in the gut—sneaky, but treatable.
Tapeworms
Often hitchhiking via fleas, tapeworms look like rice grains when segments break off. If a cat swallows an infected flea while grooming, the tapeworm life cycle begins. Good flea control is half the battle here.
Heartworms
Less common in cats but far more serious. Transmitted by mosquitoes, they lodge in the heart and pulmonary arteries. There’s no approved adulticidal treatment in cats—prevention really matters.
Fun fact: Indoor-only cats aren’t immune. One mosquito or one flea is all it takes. That’s why year-round prevention is a smart habit.

How cats pick up worms
Contact with contaminated stools or soil
Eggs can hang out in soil, sand, or litter. Curious paws explore, grooming follows, and—bam—ingestion happens. Scoop daily, wash hands, and use a good litter routine.
Fleas and grooming
Tapeworms often arrive via infected fleas swallowed during grooming. If your cat’s a meticulous cleaner (so… all of them), flea prevention is essential.
Hunting and prey
Small rodents can carry roundworms and tapeworms. If your feline has a hunter’s heart, talk to your vet about a prevention plan that matches her lifestyle.
Signs your cat may have worms
- Visible segments like “rice grains” near the rear or in stools (tapeworms)
- Vomiting, diarrhea, or a bloated tummy
- Weight loss, dull coat, or poor appetite
- Coughing or breathing changes (possible heartworm)
- Behavior shifts: lower energy, irritability, or hiding

Prevention: your easy, loving routine
Flea prevention all year
Use a vet-recommended flea product consistently (topical, oral, or collar—your vet will advise based on age and lifestyle). Preventing fleas helps prevent tapeworms, too.
Litter hygiene that actually works
- Scoop at least daily; fully wash the box weekly with hot soapy water.
- Wash your hands after scooping; a washable mat under the box catches stray grains.
- Keep children’s sandboxes covered outdoors.
Diet and home care
- Feed a complete, balanced diet to support immunity.
- Vacuum around litter areas weekly and launder bedding regularly.
- For multi-cat homes, provide one litter box per cat plus one extra.
Choosing the right deworming option can feel overwhelming. Start with this handy overview of the best dewormers for cats and what they target.
Treatments and vet care
There are safe, effective dewormers for roundworms and tapeworms, plus preventives for heartworm in cats. Your vet will pick the right molecule and dose for your cat’s weight, age, and lifestyle.
Common mistake to avoid: Don’t use dog products on cats (ever). Some dog-only ingredients are toxic to cats, and incorrect doses can be dangerous.
Another easy miss: Stopping after one dose. Some worms have life cycles that require a repeat dose—your vet will set the timing.
When to call the vet
- You see “rice grain” segments or spaghetti-like worms
- Persistent diarrhea, vomiting, coughing, or weight loss
- Your cat is a hunter or you’ve had a recent flea issue
- You live in a heartworm area and need prevention advice
Curious how long it takes to clear a worm infestation and what to do next? Here’s a focused guide on timing and effective tips.
Pro tips from one cat mom to another
- Practical, original tip: Create a “parasite planner” in your calendar. Pair flea prevention and deworming with something you never forget—like your rent payment date. Add your cat’s current weight and the product name each time, so you always dose correctly.
- If your cat is picky with pills: Try a pill pocket, a tiny smear of pâté, or ask your vet about liquid/topical options.
- For adventure kitties: Check coats with a flea comb after outdoor time and before bed.
Parasites don’t stop at fleas—ticks can bring their own troubles. Keep your feline safe with this complete tick protection guide.
What not to try at home
- No garlic, essential oils, or raw “remedies”. These can be toxic or ineffective. Stick to vet-approved treatments.
- Don’t guess the dose. Always weigh your cat and follow your vet’s instructions.
Wrap-up: a calm, worm-free routine
With steady flea control, clean litter habits, and the right dewormer schedule, you’ll keep your cat comfy and protected. A few simple habits go a very long way—your future self (and your cat’s tummy) will thank you.
FAQ
How often should I deworm my cat?
Frequency depends on age and lifestyle. Kittens need more frequent deworming than adults; outdoor hunters may need it more often than indoor cats. Your vet will tailor a plan.
Can indoor cats get worms?
Yes. Fleas and mosquitoes can sneak indoors, and contaminated soil can be carried in on shoes. That’s why prevention still matters for indoor cats.
What do tapeworms look like in cats?
You may see small, white segments resembling rice near your cat’s rear or in stools. Your vet can confirm and prescribe safe treatment.
Is there a cure for heartworm in cats?
There’s no approved adulticidal treatment for cats; care focuses on prevention and supportive management. Ask your vet about heartworm preventives suited to your area.
