Before We Begin
Natural ingredients like herbs, plant extracts, and essential oils, are not regulated by the Environmental Protection Agency (EPA). As a result, there is no guarantee that these products will be effective against insects.
Citronella, peppermint, tea tree oil, and lavender are toxic to cats. Always consult your veterinarian before using any new product on your cat, and do a patch test on a small area of skin before applying a repellent to your cat’s entire body.

Final Thoughts
There are several repellents that you can make at home to keep your cat safe from insects. The best repellent for your cat will depend on what type of fresh herb you have on hand and what scent your cat prefers. Whichever repellent you choose, be sure to apply it directly to your cat’s fur and avoid their eyes and nose. While the herbs have insect-repellent properties and are safe for cats, you might need to reapply them regularly. And remember, essential oils can be dangerous to your cat, even topically, as they will be absorbed, putting your pet’s life at risk. Therefore, we recommend that you stay clear of those products unless they are explicitly approved by a vet. Always check with a vet first to make sure your potion is safe for your cat!
