Any pet owners?

This might seem weird to those of you without pets but as I'm typing this my cat is lying on my tummy. I think he knows something is happening. He has been mega protective and hardly left my side for the last few weeks. He's even crying when I go to work and normally it's as though he can't wait to get the house to himself! In the last week he's cuddled onto my tummy at every opportunity! It certainly soothes the crampy feelings I've been having. He's like a wee hot water bottle!
