What Should I Look for When Buying Flea Shampoo for Cats?

When looking for the best flea treatment in the form of a shampoo, there are several things you need to consider.

  • Active Ingredients. First of all, you need to check the active ingredient. Ideally, the shampoo should contain natural ingredients and be efficient against fleas in different stages of the life cycle (adult fleas, flea larvae, and flea eggs).
  • Added Ingredients. In addition to the active ingredient that kills pests, most formulas have hydrating and nourishing ingredients such as aloe, oatmeal, buttermilk, shea butter, tea tree, essential oils, coconut oil, peppermint, etc.
  • No Harsh Chemicals. Chemicals like parabens, phthalates, and sulfates should not be in the shampoo. The same applies to artificial colorants and fragrances. These ingredients can be hazardous in the long run.
  • Efficacy Duration. Depending on the active ingredient, some shampoos achieve immediate flea control while others have residual efficacy – kill fleas that are present at the moment and prevent future infestations for a certain period.
  • Scent & Consistency. You should also pay attention to the shampoo’s scent, as most anti-flea treatments have repulsive scents. The consistency matters because it affects the ease of use – a very thick shampoo will not lather easily, and a very thin one can be messy.
  • Brand. Always do a brief research on the brand – a reliable brand will be transparent about its ingredients and manufacturing practices. A brand confident in the quality of its products is likely to give money-back guarantees.

  • SENTRY PurrScriptions Flea and Tick shampoo for cats kills fleas, ticks and lice.

How Often Should I Bathe My Cat With Fleas?

Vets typically recommend a monthly flea bath to help eliminate fleas, flea larvae, and flea eggs. In cases of severe flea infestations, more frequent baths will be advised.

If bathing does not help, you need to talk to a veterinarian about additional flea treatments such as tick collars, flea and tick sprays, or topical products.

How Long Does Cat Flea Shampoo Take to Work?

It is advisable to leave the shampoo on the cat for about ten minutes to let the active ingredients work. However, you need to read the instructions on the product for more details.

Consult with your vet before using a new flea shampoo for cats, as pets can have negative reactions to certain ingredients commonly found in flea and tick shampoos. Also, talk about preventing future flea infestations by using flea collars, anti-flea chews, or topical treatments.

How Long does Flea Shampoo for Cats Last?

Most flea shampoos are intended for monthly use. Based on the cat’s size and the exact bathing frequency, one shampoo is likely to last for a couple of months.

Concentrated shampoos will last longer – they lather easily and allow using a smaller amount of product per flea bath.
