Don't know why I'm posting really, I'm just so gutted and upset, just wanted to talk to people who understand.
DD got a text from a friend to say a cat like ours had been knocked over up the road. We went out looking and found him. DD was distraught, so was I. We brought him back and DH buried him in the garden.
He was only 8, a big daft ginger. He dribbled on me when he got stroked. He used to sit with his paws all wrapped around our other cat. The other cat keeps going and sitting at the bottom of the garden where we buried him. I miss him so much already. 
Worst of all, we are having a new puppy today, it's supposed to be such a happy day and I can't stop crying.
Thanks for listening.
