Defender Spikes, Upgraded Bird and Cat Repellent for Pigeon, Cat and Small Animals - Protect Your Sofa, Garden, Outdoor Walls, Anti Theft Climb, Plastic Security Fence Spikes, 12 Pack

Keeps my cats in and stray cats out. I have 3 felines and out of those 3 one of my cats likes to hop out the fence patio. The lady that lives next door her cat tries to play with my cat but she doesn't like other cats besides the other I have. With these spikes she no longer can hop out nor does the neighbors cat come over. Because my other 2 cats are also very territorial. It's easy to install depending on where you're placing it. But it serves its purpose.

Out new cat fell or jumped 15' from walk way bridge in our house. Scared the heck out of us. So, I bought and installed these spikes on the bridge handrail. This keeps the cat off of it.

Son pocos, cumplen su objetivo.

I adhered each spike with multiple zip ties on a fence, the feral cats simply pushed the spikes to the side of the fence after they landed on the spikes. I had to reposition them over and over again. Not what I want the product to do.

I had an issue with birds landing on a ledge above my window. They couldn't build a nest, but they still made a mess. I ordered these bird spikes and finally glued them in place. The very next day birds started landing on it and building a nest!!! DON'T BUY THESE!!!

This is by far the best repellant spikes I have ever used. First of all it is not metal so it will not rust and I am not going to accidently stab myself with rusty spikes when maintaining the repellant. The plastic spikes are smooth so any garbage that gets trapped by the spikes can be easily removed. I also like the low tone brown color that is inconspicuous as oppose to the shinny cheap chrome plated metal spikes. Love the product and will definitely purchase more.

Great product easy to install.

The wild birds used to land on my windowsills and leave droppings on them. These spikes really help to keep them from standing on the windowsills and give me peace of mind.
