Awe! My cat does the same damn thing! I get angry and look down at him and then all I feel like doing is hugging hum soo tightly! Your cats adorable! How old is he? Mine is about 6 months?
O that's normal.
I have three cats, two fatties who both like to lay on my arms when i'm on my laptop. One of them also does it when I'm doing my homework, not exactly usefull, but my teaches laugh about it when I hand something in, because I write around him:P
You're not the only one;)
