Wow.. That's one expensive trip... =) Good to hear she's doing better!

I'd recommend a better Kibble. I had weight issues when we fed Nutro Natural Choice. Bunny lost a lot of weight. And Eli didnt continue to gain weight as he should have at his puppy stage then... We switched to Nature's Recipe, which is about the same price as Natural Choice at Petsmart. Its better food, at least it seemed to end the weight issues here. Could get a better wet food too.. we use Ultra (Nutro product...) for Zeke... working on slowing him down while he eats. Its one of the only wet foods Petsmart had that didnt contain by products.. was the cheapest one always. Cant afford the Blue Buffalo that I'd love to feed my three.. shoot. We fed Eli cottage cheese with his kibble for a couple months too.. when he was 7-9 months or so. Helped add some weight.

Satin balls should help too tho. Good Luck!
