This a cat deterrent. It sprays air when it detects movement. It startles your cat. She will learn not to climb on countertops or tables. It’s way more effective than you telling your cat to get off the table. When you intervene, your cat just learns that’s it’s not ok to climb when you’re present in the room. And then she will go as soon as you’re away!

That’s spray worked very well with Kami but it might not work for your cat.
