Cat Spikes MKII

My jerk cat keeps coming up on counters, desks, and whatever, and knocks stuff over, pukes on my stuff, and I got tired of it. So I printed off multiples of these cat spikes, to leave around on the countertops, desks, etc, so they remain cat free. Will not harm cat per se, as though they are pointy, unless the cat jumps full weight onto them, they will be just fine. Only takes 1 time of stepping on these for the cat to realize it isn't a place they are able to be anymore.
Before anyone calls PETA, or thinks I am some sadist, let me clarify.
My cat is a big, intelligent, bored, asshole. I love the shit out of him, but for 2 years now he has been performing mental and physical warfare against me, and only me. Not my 2 sons, just me. I do everything for this cute, fat jerk, but he just won't stop messing with me. I have never, and would never intentionally harm him, but he is tough, and this worked, and didn't hurt him long term, so just calm down. lol.
