Flea repellent products labelled as ‘natural’ may still be toxic to your pet. The chemical d’Limonene, derived from citrus peels and found in many natural anti-flea products, can be highly toxic to cats. Flea sprays and dips which contain “all natural Pyrethrin” can be toxic to some pets, and Pyrethroids , synthetic derivatives of pyrethrins, expose your pet to more chemicals.
Flea control formulations which use essential oils can be particularly hazardous to cats. Essential oils are absorbed rapidly into their skin and enter the bloodstream, and because cats do not efficiently metabolize essential oils, exposure can build to toxic levels. And while there may be no initial adverse reaction, the effects of essential oils can be cumulative and manifest themselves at a later date. Other natural ingredients known to cause allergic reactions or have toxic effects in some animals include Tea Tree (Melaleuca alternifolia) oil and Pennyroyal oil.
However we can allow our regular cat-safe pet shampoo to sit for extra time on your cat to smother the fleas & sell Frontline drops that can be applied to your cat to kill & prevent fleas.
