Deworming Dogs vs. Cats: What’s the Difference? A Guide for Multi-Pet Homes

If you share your home with both dogs and cats, it’s important to know that their deworming needs aren’t the same.

Two species, two needs

Even if they live under the same roof, differences in metabolism, behavior, and grooming habits mean that each species requires tailored parasite prevention.

Understanding these differences helps ensure the health of all your pets—and avoids common mistakes.

Key Differences Between Dogs and Cats

Here are a few essential factors to keep in mind when it comes to managing parasites in multi-pet households:

Metabolism: Cats process medications differently than dogs. A drug that’s safe for one may be harmful to the other.

Behavior: Cats often hide symptoms of illness longer, which makes early prevention critical.

Hygiene: Cats groom themselves more frequently, increasing the chance they’ll ingest parasite eggs or fleas. External parasite control is especially important in feline care.

These distinctions mean that a product effective for your dog might not be appropriate for your cat—and vice versa.

Best Practices for Mixed Pet Households

To ensure safe and effective deworming across all your pets:

Never administer a dog’s medication to a cat, or a cat’s to a dog, unless specifically prescribed by a veterinarian.

Watch for potential side effects after giving any treatment, especially with new products.

Deworm all pets in the home on the same schedule to reduce the risk of reinfection or cross-contamination.

Regular vet checkups are also essential, as your veterinarian may recommend different products, doses, or frequencies depending on the species, age, and health condition of each pet.
