Great HOME Spray - Stop Using This on Your Pets!
This is a great spray for your HOUSE. The number of people who have used this on their pets is concerning - this isn't for pets. This got rid of fleas in our home quickly, in combination with pet-safe flea treatment on our pets. The smell is pleasant, though as many have said, the nozzle does leak when you spray it. The size is more than enough - I used it on all of our carpets and furniture for 3 days in a row and still have over half a bottle left.

Great value and works well
works well, great value, getting the cat to sit still is another story. We usually put it on a comb and comb the cat it seems to make it easier. It does take care of the fleas, but multiple applications are needed. Great value compared to others. The product did not show any irritation on my cat.

Gentle and effective for dogs 🐾
This shampoo lathers nicely and leaves my dog’s coat clean and soft. It helps with fleas without irritating his skin, which I appreciate. Small downside: You do need to let it sit a few minutes to work best. Good option for bath days.

Have to drown the fleas
I did a test and caught a flea from my cats. I tried to spray lightly like how the instructions said. It doesn’t kill the flea, minimal effect cuz it’s still jumping. You have to soak the flea in the spray liquid to kill it immediately. But that’s not possible with spraying the cats, it basically means you have to “shower” the cats with the spray to kill them. Smell nice and no side effects for my cats tho.

My cat hates this product and now hates me and it does not work....even after two applications.
I sprayed my 10 year old adult cat, who up until now has never had fleas, to try and get rid of the few he seemed to have. I followed the instructions spraying his entire coat and rubbing it in...even though he was not happy about the process. For the next two days my cat's coat looked terrible...like he had rolled in oil and syrup and he was very distressed. He was still scratching so I decided to spray him again even more thoroughly than the first time. I don't know if it's the smell he objects too, and I would not blame him, or what, but he would not come near me and spent most of today hiding, which is very unlike him. He even pooped outside of his liter box. I got the message....he is pi**ed. His coat still looks and smells like crap too. He seems lost and confused and is not his normal self. He has been crying a lot which I am assuming has a lot to do with the smell which he cannot get away from. I ordered a flea brush yesterday, which came today - thank you Amazon, and found multiple fleas in his coat. But I absolutely will not subject him to that torturous experience again. Especially since it appears it's not very effective. In the end this was a very failed experience for my cat and myself. There is no way I could possibly recommend this product. I am sure other cats might not react like he did, but if you care about your cat's well being, I would find another product. I am going to call the vet on Monday to get their recommendation...possibly something he can take to kill and prevent fleas.
