The typical deworming schedule
Most vets follow a rhythm like this. The right product and exact timing depend on your cat and where you live.
| Stage | How often | Why |
|---|---|---|
| 2 to 12 weeks old | Every 2 weeks | Kittens often carry roundworms from their mum, so early regular doses matter most. |
| 3 to 6 months old | Once a month | Growing explorers meet the wider world and its less pleasant passengers. |
| 6 months and older | Every 3 months | The classic adult rhythm. Hunters and outdoor cats may need more, so ask your vet. |
| Strictly indoor cats | Every 3 to 6 months | Lower risk, but shoes and windowsill adventures still carry eggs inside. |
What deworming protects against
A quick tour of the uninvited guests.
- Roundworms, the most common, especially in kittens.
- Tapeworms, often linked to fleas, so flea control and worming go together.
- Hookworms, picked up through skin or mouth from contaminated soil.
- Lungworm in some regions, carried by slugs and snails, worth asking your vet about.
Signs worth a vet chat
Cats are masters of looking fine. These quiet signs deserve attention.
- Rice like segments near their bottom or in bedding.
- A pot bellied look, especially in kittens.
- Weight loss despite a healthy appetite.
- A dull coat, scooting, or vomiting that keeps returning.
Making doses actually happen
The schedule only works if the doses do. A few habits make it effortless.
- Log each dose with the product name and date the day you give it.
- Set the repeat so the next due date calculates itself.
- Keep the reminder somewhere you will actually see it.
- Pair worming with flea treatment when your vet recommends both.
Good questions
How often should you worm a cat?+
Most adult cats need worming every three months. Kittens need it much more often at first, every two weeks until twelve weeks old, then monthly until six months. Outdoor hunters may need more frequent doses, so ask your vet.
Do indoor cats need worming?+
Yes, though often less often. Indoor cats can still pick up worm eggs from shoes, other pets, or the odd hunting victory over a house spider. Many vets suggest every three to six months for strictly indoor cats.
What are the signs of worms in cats?+
A pot belly in kittens, rice like segments near their bottom or in their bedding, scooting, a dull coat, weight loss despite a good appetite, or vomiting. Many cats show no signs at all, which is why the schedule matters.
Every three months is easy to forget. PetWrite will nudge you.
Add a worming dose once, set it to repeat, and PetWrite gently reminds you before the next one is due, right beside the rest of their little story.
