just that really - she is 14 (maybe 15, she came to us when she was about 1) and has survived a house move, house renovations, the arrival of two children, and a brief period of living with a dog. She is the loveliest, sweetest little cat. But she has gone very thin the last few months, despite eating well. She seems fine in herself - she sleeps a lot and doesn't go out that much any more, but she is still up for a bit of a play from time to time, and is happy to sit on a lap or in front of the fire of an evening. I haven't taken her to the vet in years (last time she'd broken her sternum!) but maybe it's time to get her checked over?
