Think your indoor cat is safe from fleas? Here's why even strictly indoor cats can get them — and what to do.
Yes — indoor cats get fleas too
It's a common myth that indoor cats are safe. Fleas hitch rides on your clothes and shoes, on dogs, and through open windows and screens. Once inside, they thrive in the warm, stable environment of your home.

How fleas reach indoor cats
A single flea brought in on a pant leg can lay dozens of eggs a day. Multi-pet homes are especially at risk — a dog that goes outside can bring fleas straight to an indoor cat.
Prevention is simple
A vet-recommended feline flea preventive like [Revolution Plus](/products/revolution-plus-topical-for-cats) keeps indoor cats protected year-round. Never use a dog product on a cat — some are toxic to felines.
Watch for signs
Excessive scratching, over-grooming, tiny black specks (flea dirt) in the fur, or visible fleas all mean it's time to act. Year-round prevention avoids the hassle entirely — and it's cheaper than treating an infestation.

Frequently asked
- Can strictly indoor cats really get fleas?
- Yes. Fleas travel on clothing, other pets, and through windows. Even a cat that never goes outside can become infested.
- Do I need year-round flea prevention for an indoor cat?
- Most vets recommend it. Fleas can survive indoors year-round, and consistent prevention is far easier than clearing an infestation.
