I have a window by my computer and my cats love to go by it and get a nice breeze. I don't mind them in the window or even on top of the computer monitor or printer. The issue I have is that tonight when I went to go on the computer I had an unpleasant surprise. Can you guess what it was? A hairball on my mouse pad. This is the second time this week! I would just get a new mouse pad and could and might but for now I just took the hairball off and wiped it with a disinfecting wipe.(it has a beagle on it and is just to cute to get rid of) I am hoping this will be the last time it happens. So has your cats ever left you a surprise like this? Do your cats like to be by you when you are on your computer?
