Safe for leather?
Answer by ChewySep 18, 2017
This spray isn't intended to be sprayed on furniture. To stop unwanted behavior in your cat you should spray in their direction approximately 12-18 inches away in a short burst.

How often do you have to spray this? We have some other spray that we bought and we have to spray it ever single day and it also smells pretty bad.
Answer by ChewyMar 05, 2021
Each pet is different and will respond differently to the spray. The perception of the pheromones by the cat/dog is immediate. However, visible improvement in specific behaviors may require some time, depending on factors such as individual differences in pets, the nature, duration and severity of the behavioral problem, and the types of behavior modifications being used by the pet parent. This product contains lavender and chamomile fragrance. If you are sensitive to these fragrances, you might want to have someone else use the spray and wait till it dries so the fragrances don’t bother you.

What are the ingredients?
Answer by ChewyMar 02, 2018
The ingredients are: lavender and chamomile fragrance and patent pending pheromone technology.

Lavender is known to be poisonous to cats. This product says it’s lavender scented. Is any real lavender or lavender essential oil being used in this product?
Answer by ChewyOct 30, 2019
This spray contains Lavender and Chamomile fragrance and is not real lavender or essential oils.

Disappointed - VERY Loud and Scary

I bought this because I read all the reviews and it seemed to have come highly recommended. I have a young lad (8 months old) who constantly terrorizes my poor 8 year old little Cali. I know he's still young and wants to play, but wanted to see if I could get his menacing behavior somewhat corrected because I felt sorry for her getting stomped on all the time. Well, I only used it once and believe me when I say scared the poop out of me and the two cats as soon as I 'sprayed' it once. It doesn't just spray a pheromone scent it also makes a horrendous loud noise that probably woke up the neighbors too! I did read it made a "noise" but never expected it to be that loud. For me, I would not recommend this product unless you are breaking up a mauling of your cats.

Needed help

Stop That is the only thing that has worked for my kitty. He’s about 8 months old and a real climber. Before Stop That he had knocked items off shelves and even pictures off the wall! Now all I have to do is pick up the can. It has worked miracles with my kitty.

Works, but at a cost.

This spray works for us. We have a very misbehaved cat that occasionally needs reprimanded and we think this is better than the spray bottle method. We have been using the "stop that" spray for years. It used to be a third of the price. I also have noticed the can has been shrinking, with less sprays for your buck. Such a shame! I will continue buying here and there, but not as much as I used to due to the huge prince increase and quantity decrease.

Worked great at first

I was desperate to find a product that would stop my 7th month old male kitten and yes it did at first. But this “ kid” doesn’t stop his bad behavior! It may be because he’s still a kitten and learning but I may need to find something else along with this product

Bully Buster

My two 4-year old kitties have been bullying my senior kitty. This product stops the queen bully in her tracks. Now, I just have to pick up the can and she scrams. The other trouble-making kitty isn't afraid of the noise but I think the pheromones calm her a bit. I gave this product four stars because it's expensive. Worth a try for some peace in your household!

My cat hates it

I was surprised by how effective this thing is. My cat Mr. Bojangles is super freaked out by it, to the point where he runs if he even sees me reach for it. But just one or two quick bursts from this thing effectively taught him to stop boxing his dog sister in the face at dinner time, so it did its job as advertised. I only use it when the cats are doing something that REALLY needs to stop, and that seems to make it more effective too.

The sound works well (it’s just a loud blast of air), but the pheromones don’t work for my cats at all. On top of that, it smells like stinky armpits and the smell lingers for so long. I will try something else.

Single cats, maybe

I have four cats. It's tough to use this without traumatizing all of them. Sadly, it uses the same pheromone scent as a the calming spray we bought from Nature's Miracle and calming collars, so now, I spray the calming spray and my 3 -year-old cat freaks out and runs away. The one or two times I used the "Stop That" was for actual "cat fights" to break it up, and it literally scared them so badly, they were in hiding for hours. I don't know that this works with more than one cat. Even then, it's pretty terrifying. I've just started hissing at them. Same effect, and while the product has a pleasant enough scent, it's now a trauma trigger for my cats. Problematic when it's supposed to calm them. How confusing... It's too bad it's not a brief, sound (quieter, too) w/o the scent. It feels like spanking your kid while saying "I love you."

My bad cat is terrified of this so it's a win

All I have to do is ask my bad cat if he wants to get canned, and he knows that means this "Stop That" spray. I don't spray it often because of the cost, which is why I am giving 4 stars and not 5. It does not last long at all. But luckily, I just have to show it to him, or say the word "can". He knows what it means. I bought a few of these when they were on sale. I am not sure if I will buy it again at the current cost. The only problem is, my bad cat now picks on my girls when I am in bed or not around. I even saw him having my one girl cornered in the litter robot. I wish I could have a robot follow him and make the loud sound of this spray or ask if he wants to get canned. Trying to figure out away to get Alexa to do it.

What a waste

Froze up and stopped working within a couple minutes. It has to be one of the worst items I have ever ordered from Chewy
