Hi there My ferret Mason has become obese in the last year, he stopped eating as he wasn't able to pick up food and eat it (the vets couldn't find anything wrong, he's seen 3 different vets). I now feed him 3 times a day and he eats about 3 teaspoons full of ground ferret food with water and yet he puts on more and more weight. He now looks like my ferret Jilly who is on prednisolone and also looks like my friend's ferret Ben who was on pred and had a huge tummy full of water because of the pred. Mason's tummy looks like Ben's tummy except that Mason is big all over but especially his tummy is sooo huge! I don't know if there is any fluid, the vets didn't seem to think so and said there may be a little bit but that was 2 months ago and his tummy has got bigger again. So I was wondering whether there is any disease where ferrets over-produce a steroid like pred? Mason doesn't really eat enough to keep putting on weight... He's healthy apart from the weight problem and has just shed his winter coat and has a new beautiful summer coat. And he still plays with the others... All the best to everybody and their kids.
