Here's why:
* Exposure: Cats can get worms from a variety of sources, including:
* Fleas: Some types of worms, like tapeworms, are transmitted through fleas.
* Eating infected prey: Cats who hunt and eat rodents or other small animals can pick up worms.
* Contact with infected feces: Even indoor cats can be exposed to worms if they come into contact with infected feces, for example, through shared litter boxes.
* Immune System: While adult cats have a stronger immune system than kittens, it's not foolproof. They can still become infected, especially if they are exposed to a high number of worm eggs or larvae.
Important Note: It's crucial to have your cat regularly checked by a veterinarian, even if they are an indoor cat. A veterinarian can recommend appropriate deworming medication based on your cat's age, lifestyle, and any potential exposure risks.
