Our daughter got a second ferrret "Peanut" four year ago because she had one ferret and thought it would be nice for him to have a companion. They were inseparable. She went away to visit a friend three months ago and when she left "Peanut" was fine. But then a month ago I picked him up and notice he was very thin. He went to the vets where they nursed him back to health. I thought all was fine until a few weeks went by and he got sick again. He went back to the vets and was diagnosed with kidney failure. The vet told me how to treat him at home but that it would be progressively deadly to him. We left on a Wednesday morning to go across country to pick up my daugher to bring her home for the holidays, and I gave "Peanut his medicines and made sure he had everything he needed to sustain him until we got back the next am. We got home aroung 6 am and my daughter wanted to see him so I took him out of his cage. She was very upset to see how sick he had become, but I assured her we would do all we could to try to nurse him back, as much as could be expected. She called his name and he looked up at her and she scratched his little head. After giving him his medicine I put him back in his cage under his little blanket. When I went to take him out later in the day, thats when I found he had passed away. I know in my heart that he held on just long enough to see her on last time.
