Instead, you could comb the fleas off the cat with a flea comb then submerge the fleas in a small container of soapy water. This would also be a good alternative for cats who love being groomed but who violently refuse baths or the application of a spray. Before using ANY product on your cat, read the label instructions completely. If you do not completely understand the instructions, you should contact the manufacturer or your veterinarian for clarification. Observe the species and age requirements listed on the label.
Cats react very differently than dogs to some insecticides.
Some dog products can be deadly to cats, even in tiny amounts. Use caution when using products that contain organophosphates in your house or on your cat . Cats are more sensitive to organophosphate insecticides than most other animals. Currently, there are few flea products in the United States labeled for use on cats that contain organophosphates as an active ingredient. The few that can be used on cats contain a small concentration of organophosphate.
