Parasiticides for Cats

Reviewed by Dr. Angela Beal, DVM

Cats can be exposed to a variety of internal and external parasites throughout their lives, even if they spend most of their time indoors. Fleas, ticks, heartworms, intestinal worms, ear mites, and other parasites can affect your cat's comfort and overall health, making year-round parasite prevention an important part of routine care. Parasiticides for cats are formulated to help prevent or treat specific parasites, and some products provide broad-spectrum protection against multiple types of parasites in a single dose.

At Chewy, you'll find a wide selection of cat parasiticides prescribed by veterinarians to help protect cats at different life stages and lifestyles. Our assortment includes topical treatments, flavored chews, oral tablets, and other easy-to-administer options that may target fleas, ticks, heartworms, intestinal worms, ear mites, or a combination of parasites. Because every product has a specific spectrum of activity and dosing schedule, your veterinarian can help determine which option best fits your cat's needs based on their age, health, environment, and risk factors. Here are some important things to consider about parasiticides for cats:

• Parasite coverage: Products may protect against fleas, ticks, heartworms, intestinal worms, ear mites, or multiple parasites with a single product
• Treatment format: Choose from topical solutions, flavored chews, oral tablets, and other veterinarian-approved options
• Broad-spectrum protection: Some parasiticides help protect against several types of internal and external parasites at once
• Life stage and lifestyle: Your veterinarian can recommend a product based on your cat's age, health, and weight, and whether they spend time outdoors
• Year-round prevention: Consistent parasite protection helps support your cat's health throughout the year

Protecting your cat from parasites starts with choosing the right product for their individual needs. At Chewy, you'll find veterinarian-approved cat parasiticides from trusted manufacturers, along with convenient home delivery.
