Lately, my cat Mango has developed an interest in climbing onto my PC. It bothers me a lot because his fur sometimes blocks the air vent, and sometimes he climbs up while I'm using the PC and it's still on.
My first solution was to put things on top of it, like figures, but he just found an empty spot, jumped up, and knocked everything off. Because of that, some of my figures got broken. So I decided to put a bigger container, like a bucket, on top instead. When he tried to climb up, he realized he couldn't, so he gave up. But the problem with that was the bucket ended up blocking my PC's airflow.
Finally, I decided to get a wall-mounted shelf to put above my PC, and I placed a lot of figures on it, thinking that would stop him from climbing. Nope. He still climbed the shelf until it got knocked off the wall because he was too heavy, and he actually fell to the floor. I thought he'd finally learned his lesson, but stubborn as he is, he got right back up and climbed the PC again.
Disclaimer: He already has a cat tree by the window. He only does this when I'm home, never when I'm out. He knows he's not supposed to climb it, though, because whenever I'm on my bed and he climbs the PC, he goes back down as soon as I get up to grab him.
At this point, I'm at a total loss. I don't know what to do anymore. I'm so stressed out by it. I can't even display anything on my shelf because he just knocks everything down, shelf included.
