This flea spray for cats gives cats quick relief from fleas.

The spray 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.

How To Use The Cat Flea Spray – It can be sprayed directly onto the cat, 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 spraying at the neck area. Ruffle the coat and spray against the natural lay of the hair.
Further instructions about how to use cat flea spray 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 about using this cat flea spray contact your vet.

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

Pros

This cat flea spray even works well in very hot humid areas.

Cons

This cat flea spray can only be used on cats or kittens over 12 weeks old.
