Flea & Tick for pets
Preventive treatments and control products for external parasites.
Flea and tick products range from spot-on treatments and collars to shampoos and environmental sprays. Some are sold over the counter; others need a prescription. Products are formulated for a specific species and weight band, and that matters more here than in almost any other category.
When to seek veterinary care
Some products made for dogs contain permethrin, which is highly toxic to cats. Never apply a dog product to a cat. If a cat has been exposed and is drooling, twitching or unsteady, contact a vet immediately.
If this is an emergency, contact your veterinarian or an emergency animal hospital now — do not wait, and do not buy a product first. In the US, ASPCA Animal Poison Control is available 24/7 on (888) 426-4435.
When to contact a veterinarian
- Tremors, twitching or seizures after application
