Maybe not all cats act up. Maybe its only the ones that want attention. I give my kitty Amber plenty of attention, but I guess its never enough. She just can't get enough pets and snuggles I guess. I was trying to get some work one one day, when the bratty lil kitty kept climbing on me and getting in the way. When she knocked my bottle of water off my desk, I knew I had to do something. I think she was in heat, because when I started fingering her hole she went wild! Once I started stroking her too, it wasn't long before she squirted all over me!
