Q. Put Freedom 45 on cat by mistake, and cat is now very sick. What should I do?

Answered By

A. A typo: Flea products designed for dogs can be toxic to cats, flea products designed for cats should be safe if given in the correct dosage*

Answered By

A. Flea products designed for pets are toxic to cats and should be brought to your veterinarian or emergency clinic immediately. These products can cause a number of severe reactions ranging from skin burns and sores to full-blow seizure, coma and death.

If you applied the material within the last day you may be able to wash off the excess to prevent continued absorption of the product. However, if your cat is already showing signs of illness, contacting your vet immediately is needed.
