Why Indoor Cats Can Still Get Parasites

1 How Indoor Cats Get Parasites

Many owners think a cat that never goes outside is safe from parasites, but indoor cats can still be infected. Mosquito bites, contact with cockroaches, raw meat, and houseplants all pose risks, so routine deworming remains important.

Even if a cat stays home, owners can carry parasite eggs indoors on their clothes, shoes, and belongings. Mosquitoes moving through the home can bite and infect the cat. Houseplants, raw food, or cockroach contact can also introduce parasites. Because the routes are varied and some parasites are zoonotic, regular deworming protects both the cat and the owner.

2 Parasites to Prevent

Routine deworming targets the parasites cats commonly catch, which fall into two groups. Internal parasites include roundworms, hookworms, tapeworms, and heartworms. External ones include fleas, lice, ticks, and mites, and these are more common in spring and summer. Cats can also contract nematodes and toxoplasma, which may spread to people after infection.

3 Deworming Correctly

Internal medications are usually oral and easy to dose. External products work by spreading through the skin’s oil glands, so they are simple to apply at home without a clinic visit.

Products come as internal, external, or combined. Oral internal dewormers are typically given every three months, or more often for cats that eat raw meat. External drops are placed on the skin after parting the fur at the back of the neck; avoid touching the cat for two to three hours and do not bathe it for three days. Combined drops use the same method. Free-roaming cats or those that visit gardens and grass should be dewormed monthly.

In any environment, deworm your cat on a schedule to avoid parasitic disease. Control the dose strictly by the product label and the cat’s weight, because these drugs are toxic in excess and an overdose can poison the cat. Never be careless with the amount.
