Not at all! Cats and dogs do not belong to the same species and they are as different from each other as a rabbit from a horse! Especially, they have a different metabolism and a different physiology. In other words, what can be safe for one, can be a deadly poison for the other one. Cats are fragile animals and a large number of chemical substances cannot be eliminated by their liver. So, it is very dangerous to take a risk in regards with this question; numerous cases, some with tragic ends, have happened. It is the reason why you need to use the products specifically designed for your pet. They have been studied and developped to be safe to their health and for their well being. If you have any doubt, please contact your veterinarian before doing anything. He is a specialist and he will know how to direct you.
