Hey! Our regular ferret food got discontinued and we got a different kind with similar nutrition. Both brands were thoroughly researched nutrition/ingredients wise. I don't feed crap to ferrets. My 6.5 year old male ferret is an extremely picky eater and, as expected, hated new food. I left one bowl with new food mixed with old and 1 bowl of old food in the cage. I haven't seen him eat in the last couple of days, usually he runs to the bowl every day at the cage cleaning/food changing time. Though, I don't normally monitor his eating. The bowl is always full, he and his sister eat whenever they are hungry. Today i noticed that he appears pretty weak when he walks. To feed him I crushed his old food with a hint of peanut butter and water and he licked couple of tablespoons. He slept mainly all day. I am planning on spoon feeding him tonight, but i am off to work tomorrow. Is the smell of new food being in a cage enough to turn him off his old food? I don't understand what is happening. He just had a vet check up and appeared healthy, except for a potential early signs of adrenal disease (he has rat tail). Vet said not to worry about adrenal, until he starts loosing fur on his body and violently scratching. He isn't scratching too much and still has all his body fur. Other than that he has always been perfectly healthy. Just a very picky eater. He actually gags if he smells food he doesn't like. Can new food can be so disgusting to him that he will starve himself?
