How often do you need to apply it if your cat is an indoor/outdoor cat?

Answer by Chewy • Sep 04, 2023
This pet spray can be used to prevent and treat an infestation at any time of the year, but should not be applied for more than 3 consecutive days. Repeat as necessary, however, the product should not be used more than once daily.

If my cat licks his fur, is there a problem with that?

I could not use this product. I could not nor could my husband get the sprayer to work so I returned it. There is no reason they could not make it more customer friendly as the ingredients seemed so good.

Couldn’t get it to spray

I think it would have worked but the sprayer didn’t work.

package title

pretty good treatment but it works in a different way, i sprayed it on a few fleas and it knocked them down right after i sprayed them, i put them in a container

pretty good treatment but it works in a different way, i sprayed it on a few fleas and it knocked them down right after i sprayed them, i put them in a container to see if they were really dead, and they came back to life and then died 15 minutes later. as long as it worked is all that mattered.

Not Effective

Have a cat (short haired) wearing a soresto collar for 3 weeks and I'm still combing 1-2 dozen fleas off him per day so I added this to his treatment. Great smell

Have a cat (short haired) wearing a soresto collar for 3 weeks and I'm still combing 1-2 dozen fleas off him per day so I added this to his treatment. Great smell. Cat was very cooperative and spraying is pretty quiet so I was able to spray directly on him and massage it well into his fur. Made no difference in the amount of fleas on the cat after 3 days use. I love cedar so makes a lovely air freshener and cat deodorant but the fleas are unimpressed.
