She looks a teeny weeny bit overweight Gareth, but just a teeny bit, nothing to worry about at this time of year. Just when i compare these recent photos to those you posted on the 21st. Can just be whilst you and her get used to new food, feeding amounts, exercise etc. Or just the camera shots. But don't go changing anything for a while yet anyway, till she levels out, so you have a baseline to work from. Her coat looks in fantastic shape which is a good indication of care, and she is positively smiling
Is she neutered?
