I used to stay up until 3 am working on projects for work, but lately when I'm at home, the cats dominate my time. I don't feel too bad about this, but it's a radical change. I'll start working on the computer and then I'll hear the sound of the cats doing something and it will grab my attention. One of the boys will walk by and I'll pick him up and put him on my lap. If I start to type, the boys will take an interest and jump up on the keyboard.
Sure, I could turn them away, but if they take an interest in me at this point, I want to encourage that kind of behavior.
