Pyrethrum, derived from the flowers of the pyrethrum daisy, is a natural insecticide commonly used in pest control products. While generally considered safe for humans, pyrethrum can be toxic to pets, particularly cats. The signs of pyrethrum poisoning in pets vary depending on the animal and the concentration of the product.
Cats:
- Severe Symptoms: Cats are highly sensitive to pyrethrum and can exhibit severe symptoms, including excessive salivation, vomiting, agitation, tremors, seizures, and difficulty breathing. These signs can appear within minutes to hours after exposure and can be life-threatening if not treated promptly236.
- Common Causes: Pyrethrum poisoning in cats often occurs when dog flea and tick products are applied to them by mistake. Even small amounts can cause severe reactions7.
Dogs:
- Milder Symptoms: Dogs are less sensitive to pyrethrum than cats but can still show symptoms like excessive drooling, gagging, vomiting, lack of appetite, and agitation. In some cases, dogs may experience paresthesia, a tingling sensation on the skin, especially where the product was applied46.
- Treatment: For both cats and dogs, treatment involves decontamination and supportive care. There is no specific antidote for pyrethrum poisoning, so prompt veterinary attention is crucial13.
