12 Pack Scat Mat for Cats – 16 x 13 Inch Cat Spike Mat with 1 Inch Spike is A Perfect Pet Training Mat Device for Cat Repellent Indoor & Outdoor to Deter Cats & Other Animals for All Seasons

I only ordered these as a last resort after trying for 8 months to keep my new fur-baby kitty off of the counters and then working her way up to dangerous heights and places. So when I received these I placed several on the floor in front of her and I stepped on it and then yelled OW! It does hurt. Then I showed her me placing them around all over the counters with the edge of them showing (so she would know they are there) and I explained why I was using them to keep her off. I left the one on the floor for her to try which she did and quickly withdrew her foot. I later saw her trying to power her way through it unsuccessfully. She was still trying it the next day. She tried once jumping up but quickly rebounded off. She never acted injured afterward but now she no longer tries. However she still looks for the edges of them hanging over to show her they are still there. She has grown and is now about one inch short of touching the overhang which I believe she plans to try to pull down when I am out or sleeping. We will see. If she succeeds I will post my solution. Please be sure they understand you still love them. I bought mine some tunnels to play inside of. One in the kitchen and one in the living room which have helped to preoccupy her attention.
