Cat Scat Mat Indoor Spiked Mat Network Digging Stopper for Garden Fence Keep Pet Dog Cat Off Couch Furniture (12 x 79 Inch, Black)

My only complaint are the hooks. You would do better buying the metal landscape hooks to anchor this mat down. The metal hooks are a better hold. We have a lady in our neiborhood that feeds stray animals and at night they sleep in her neighbor's flower beds! Ugh... And I plan to buy more, very soon!

my neighborhood has several feral cats. A couple of them has been hanging around my patio. They ruined 2 differnt sets of chair cushions. I tried all the hone remedies, vinegar and water, citrus sprays etc. Nothing worked to keep them off . I found these scat mats , delivered next day , placed them on my patio chairs and so far they seem to be working ! The prongs hard plastic , wont harm the cat but deters them from getting on my chairs. The only downsize so far is they are small and if I want to sit outside I have to move them off my chair and put them back on.
