Dog flea treatment causes cat deaths
Valerie Elliott
Hundreds of cats are dying because owners are giving them powerful flea treatments designed for dogs.

Vets have warned the country’s six million cat owners about the dangers of using dog flea treatments that contain permethrin.Exposure to permethrin results in death for one in 10 cats, said the Veterinary Poisons Information Service Exposure, part of Guy’s and St Thomas’ NHS Foundation Trust. Cats can suffer by coming into contact with a dog that has been treated with permethrin. Vets have urged pet-owners to keep flea-treated dogs away from cats for at least 72 hours and to use separate brushes and other accessories.

Permethrin triggers a violent reaction in cats. Within three hours of exposure they can suffer from nervous tics, convulsions, breathing difficulties and fits. In serious cases cats require intensive care for three or four days and without pet insurance cover, owners may face bills from £300 up to £1,500.

thanks for the warning Karlin. Knew that the treatment for dogs was dangerous for cats but never knew it could be dangerous for the cat to be in contact with the dog that was just treated. I am doing my lads later today so glad of the warning.

I was about to treat Belle the other day - with a product I got from P&H - Luckily I saw the warning on the packaging before I applied it!! I never knew a product could be so fatal. Belle is with Bambi (my cat) 24hrs a day-I dread to think what would have happened!
