Amusing thread...I'm having the same problem. My boy cat aged 5 has always thought of me as his mummy but it's got worse with this pg. He constantly sits on my belly which is huge and he weighs 9kgs and every time he sits on me bubs gives him a huge kick and Nemo just purrs louder. He follows me everywhere and sleeps in between my legs. I've been getting those agonizing leg cramps for the last 4 weeks at night and if I get one when he's in between my legs, I can't reach my toes to pull them back towards my body. My hubby has to then extricate all 9kg of cat from my legs, whilst I'm squealing about the pain
He is currently sitting in my chair waiting for me to sit down but as I'm at the computer he has to make do with my chair. He also wakes me with licking my face which I think is gross, it also makes me wheeze but to him he just loves me and wants to kiss me. It doesn't matter to him that I've already been up 5 times to pee and I've only just got back to sleep

He just wants to show his love.
Cats are funny creatures there's no denying it, but we love them just the same.
