Pay Attention to Me!

This is the reason I don't get much done on the computer lately. He has never done this before, but now it has happened at least twice. I think I give him plenty of attention but now I think he is jealous of the computer. If I try to use the mouse, he will snap at my hand, and he won't let me pick him up to take him off the desk. Sometimes he just wants me to go in the kitchen and give him food, and does this to make sure I notice because I have to stop what I am doing.
