Do flea collars make cats sick?
On One Hand: It Is PossibleFlea collars contain organophosphate insecticides, which can be toxic to cats, according to the Natural Resources Defense Council. Some cats lack the ability to metabolize the insecticides, which can lead to illness. Cats are especially prone to harmful effects due to their fastidious grooming habits.On the Other: Take PrecautionsNot all cats will get sick from their flea collar. When you put the flea collar on the cat, cut off any excess that they may be able to reach. Watch the cat carefully for any signs of a reaction like a rash or digestive upset. Make sure the cat isn’t able to groom near the collar. If he can reach it, move it or take it off.Bottom LineOrganophosphate insecticides are the chemicals on flea collars that kill fleas. They are dangerous chemicals, for both pets and people, especially children. You can take precautions to prevent your cat from becoming ill, but a wiser choice would be to avoid flea collars altogether.
