What to Look for in Flea Shampoos

To prevent cat toxicity, Lisa Tanner, DMV, a veterinarian based in Alpharetta, Georgia, recommends one labeled for cats and dogs. It is also important to read the directions carefully to ensure that they can be followed correctly.”

Ingredients

There are basically two types of flea shampoos: those that use synthetic chemicals and those that use essential oils. If you prefer natural products, look for essential oils, but formulas with pyrethrins or permethrins last longer and are stronger. Pyrethrins are derived from the chrysanthemum plant and permethrin is the synthetic version. Talk to your veterinarian if your pet has any allergies.

Lifestage

Our research revealed most flea shampoos are safe for puppies 12 weeks and older, but check the label carefully. Avoid using a flea shampoo on a young puppy because it could be too harsh on his growing skin.

FAQ

Does flea shampoo work?

Flea shampoo with medicated ingredients will kill fleas for a short time. A natural shampoo with essential oils or Dawn dish soap (a favorite of animal shelters and rescuers) will only kill the fleas that are already on your pet, according to Dr. Lisa Tanner, but won’t provide any residual protection.

What should you look for when choosing a flea shampoo?

For prevention of accidental cat toxicity, Tanner recommends one labeled for use on cats and dogs. Read the directions carefully to ensure they can be followed completely.

Is flea shampoo good for cats?

Cats do not like baths, so a topical flea product applied monthly to their fur will likely be recommended by your veterinarian. Flea shampoo can be used on cats, but many do not like to bathe, so there may be an easier way to treat them.For fleas to be eliminated, it takes a minimum of three months of treatment, and we recommend a full six months of topicals along with treating the environment and all pets (dogs, cats, rabbits, ferrets, etc.).

Will lice shampoo kill fleas?

It may be tempting to grab another product if your pet is itching, but why do it? Lice shampoo, for example, can kill fleas, but it isn’t approved for animals, so it should not be used.
