Best Flea Spray For Cats – Reviews

1. Adams Plus Flea and Tick Spray (Cats And Dogs)

Adams Plus Flea and Tick Spray for Cats and Dogs, 16 Oz

This spray helps give quick relief from fleas. It contains an insect growth regulator which breaks the life cycle of fleas for up to two months. This is not a natural product and like any chemically formulated flea product it is important to read the safety precautions outlined before use.

It is safe for cats or kittens over 12 weeks and as a bonus the product is also suitable for dogs and puppies over 10 weeks old.  Double duty if you are a cat and dog household.

It kills flea eggs, adult fleas, flea larvae and ticks and only needs to be applied once per month.

To use – It can be sprayed directly onto the cat if desired, taking care to avoid the eye area. When spraying directly onto the cat, cover the cat’s eyes with your hand. This is to avoid any unforeseen overspray. Start at the neck area. Ruffle the coat and spray against the natural lay of the hair. Further instructions are given here (scroll right down the page until you get to Important Information).

The spray can also be applied to a brush or comb and then applied to the cat if this will be easier for you.

As this is full strength preventative it is recommended to not combine this with other flea preventative measures.  If in doubt contact your vet.

Once the liquid is dry it is quite okay for family members to have normal contact with the cat.


This spray even works well in very hot humid areas.

Some cats and kittens may find the smell of Cedar too strong.


One question the manufacturer is often asked is – is Cedar Oil toxic to cats? Here is their reply.

A flea tablet or pill is normally a one off treatment that effectively treats a flea infestation and works quickly.

Our Recommendation is…

1. Adams Plus Flea and Tick Spray

We recommend Adams Plus because it repels mosquitoes, and helps kill adult fleas, flea eggs, flea larvae and ticks so stopping the constant scratching and itching.  It also only needs to be used once per month for cats and kittens (over 12 weeks). It contains an Insect Growth Regulator that stops the flea life cycle and helps prevent new infestations from forming.

This is a chemical formula so do read the precautions if an adverse reaction is noticed.  

If your cat already has a history of reactions to chemical flea products you need to source a non chemical option.  We hands down recommend Vet’s Best for overall satisfaction.  It will need to be applied more regularly than Adams spray.

How To Use Flea Spray On Your Cat

  1. Spray the product onto a washcloth or cotton ball and rub the product into your cat’s fur around the head area, taking care to avoid the eye area.
  2. Fluff up or ruffle the coat when applying the spray to other parts of the body. Spray against the natural fur growth to ensure that the product is reaching the skin – after all this is where the fleas are heading.
  3. It may help to have another person holding the cat if the cat is not used to spray being applied. It can be difficult to both control the cat and apply the spray.  
  4. Make sure the entire body is covered. The fur should be fairly wet.

5.Let the product dry before allowing the cat to lick the fur or groom. Not all that easy to do!
You could use a cone collar like the one below. The cat may be put out but you will be confident knowing that no surreptitious licks are going to take place. Plus, they look kinda cute, not draconian. I know doggos are shown but they are quite okay for cats also.

Why Use Flea Spray For Cats?

A cat flea spray will work immediately. If you are about to venture into flea territory and your cat has no other flea protection, a flea spray is a quick way to ensure protection. Sprays are inexpensive. Sprays are easy to apply.

Is Cat Flea Spray Better Than Drops?

A cat flea spray will give fast and quick relief for your scratching cat. Some flea sprays are effective for 30 days and some need to be reapplied daily.  This is largely because the longer lasting sprays will have a chemical base whereas the sprays that can be used continuously will often have a plant base.

Flea Drops give protection for a month at a time. Personally I find the flea drops are very easy to apply, easier than a spray but sometimes a spray ills the need at the time.

Flea spray is the perfect convenience product to have at hand in the event that you notice a flea problem and you want to take immediate action. In this case, I would recommend Adams Flea Spray.

Tips For Using Cat Flea Spray

  1. Part the fur.  Look for the black or reddish color specks that indicate fleas.
  2. Hold the flea spray approximately 3 inches (or as per manufacturer’s instructions0 from the cat and spray thoroughly to soak the area. Ruffle the coat as spraying to ensure the spray has contact with the skin.
  3. Use a cat flea comb to comb through the fur.
  4. Use a flea spray for the home to kill the eggs and larvae that you can’t see.
