Natural Chemistry De Flea Shampoo (16.9 oz) kills fleas on contact! De Flea Shampoo does not use pyrethroids or similar chemicals to achieve results, so fleas and other parasites do not become resistant, thus, the product never loses effectiveness. DeFlea Shampoo can be used on any age puppy or kitten!
NOTE: When using on cats, we recommend that the cat be rinsed (especially in the face area) and dried after application. This will prevent ingestion of large quantities of the product during the kitten’s normal self-grooming process. It is vital for young puppies and kittens to maintain a normal body temperature. Take precautions to provide a warm environment during and after bathing.
