Thanks for the info. Next feeding I will keep this in mind and get her to a good weight. I feel bad, as she looks like a normal size when she has just been fed, but after she digests it, it goes back to very spiney and you can see the poor thing's ribs.
I guess I just have to count my lucky stars, as I don't see any sign of mouth rot or an RI on her, which I wouldn't have been surprised about. It seems the store stressed my poor girl out!
