I did the middle one and it seemed too much for her tiny body... I gave the vet a fecal sample over 2-3 weeks ago, he gave her a clean bill of health, but I see no changes. I haven't even seen poo in 3-4 days. To be completely honest, She looks very bloated to me compared to the pictures I've seen of an AGTF. I don't think she is supposed to look the way she does but I may be wrong.
