I was down to two ferrets, one I loved to death (Mr. Stubby) and Ricky (who was not my favorite because he had killed my Sun Conure and bit the female ferret I had who died earlier in the year in the eyeball and half blinded her). Mr. Stubby was a sweetie who let me hold him like a baby in my arms and pet him for awhile and then he wanted to run around and play. Ricky was a ferret I saw on Craigslist I had wrote about way earlier and he is a fat sassy boy as was Mr. Stubby.
I noticed Mr Stubby wasn't as fat as he usually was Then I noticed he wasn't eating like he normally did. I attributed it to the food change I made. But he still wasn't eating. I took him to the Vet and he put him on medication thinking he possibly had Adrenal Gland Disease which is a common ferret disease. He had thinning fur which was one of the symptoms
