Update on Silent Bob. We have been feeding him via syringe and he has gained approx 11/2 oz which is great. Decided to hold off on taking him to the vet as I have narrowed down his recent history. A total of 3 VETs have seen Silent Bob over the past month and all have said the same.....No underlying reason. Am going to persevere with syringe and hand feeding until he gets a bit more weight on him. (truth is am frightened we won't bring him home from VETs) I have tried him with chicken wings no way, a bit nervous about the derfosted mice.....Reason one of ours mistakes TOES for baby mice, will try him when he is back on solids if I can...lol Before I forget his POO is getting better and all you ferret lovers know POO is mega important it isn't solid but has shape and is a good colour..Yipee!!
