I'm so sorry about your ferret....we almost lost a ferret with something very similar a few years ago. The x ray showed so much gas that no one was sure at first what to do..luckily our vet at the time also treated farm animals. I guess this is something that cows often suffer from and there is a tool...almost a funnel... that when put in the mouth and throat it actually burps them. She had to make one to fit our ferret and from what we remember was a tubing of sorts....she put our ferret out, inserted this make shift appliance and it worked to take all the gas from him immediately....he went back in to x ray and his stomach was now normal....it was amazing! I have the vets new number..she has moved but I know would be more than happy to explain this to your vet. Please mail me and I will provide you her number.... best wishes and I suggest you move very fast on this.... love to you both, Tara [Posted in FML 6110]
