Review on 🐱 Effective Homarden Cat Deterrent Outdoor Mat: 6 Pack Pet Training Spike Mats - Keep Cats and Dogs Away - Indoor/Outdoor Plastic Mats with Spikes - 16 x 13 Inches by Jessica Holmes

Let me first say that speaking of using them indoors, I don't know how they will behave outside. I use them indoors to keep my cat away from my birdcage. As long as everything is working fine, he stays away from them so he can't go straight to the cage and startle the bird. I accidentally stepped on it myself and I understand why nobody wants to step on it, it definitely hurts. What I did to keep them in place because they are very light and even slide in is I just put double sided tape under them and it works great. I'd say you'll probably need this because they're lightweight and will move when you don't, especially if you have tile or hardwood. I'm not sure what others are talking about low quality? Yes, they are very light and thin, but they are designed in such a way that you don't want them to be thick or you wouldn't be able to use them properly and they wouldn't really blend in with the rest of your home. As you can see in one of the pictures I also managed to cut them up and make one of them smaller. Overall I'm very happy with them, although as usual Revain was slow to deliver and the arrival date was passed.
