Yes, it IS the extra food - and especially the kitten food she steals from Lily!

I took her to the vet today and she said it's no water retained, it's all fat! She weighs 5,3 kg btw which is 11,7 pounds. (she hopes Jack won't read this!)

I've got a diet food for her now and it will be a bit complicated to feed them apart from each other. But it's definitely better than having a sick kitty!
