Thanks guys. Just wish I knew what happened to her. She seemed so happy yesterday, purring really loudly after I gave her some treats and snuggling up on my lap. I just wasn't expecting this at all.
Sorry to put a downer on the thread, just needed to get it off my chest. At least she was content and happy till the end and was actually 17 not 15, so had quite a long life. Going to bury her under a tree in the garden she used to like sleeping under and plant some bluebells on top tomorrow.
MR_Punk, Thats adorable.
Going by the age could have been anything, maybe she caught a chill etc
