Flea Control Around Cats: Why Some Products Are Dangerous

Cats process chemicals differently from dogs, and some flea products that are safe for dogs can seriously harm cats.

The short answer

Never use dog flea products on cats, and avoid essential oils such as tea tree, which can poison cats. Some ingredients in sprays, collars and home treatments are toxic to them. Use only products labelled for cats and recommended by your vet, keep cats away from treated surfaces until dry, and tell any pest control professional that you have cats so suitable products and precautions are used.

Common dangers

• Dog spot-on products used on cats.
• Essential oils, especially tea tree.
• Some sprays and foggers.
• Cats licking treated fur or surfaces.

Safe approach

1. Ask your vet for a cat-safe product.
2. Check the label for species and weight.
3. Keep cats out of treated rooms until dry and aired.
4. Wash bowls and bedding as advised.
5. Tell the pest professional about cats.

Signs of poisoning
