Ferret with insulinoma needs food advice

[Ashleyp1691]

My furbaby was recently diagnosed with insulinoma. I've been giving prednisolone but still doesn't have much energy and doesn't "play" anymore. She will be 6 in a little over a month. About a week ago I started giving her beechnut chicken baby food as a treat, but the past few days she won't eat her kibble and hasn't drank her normal amount of water. Is she just being picky and stubborn? I've been giving her a mix of water, kibble, and chicken baby food 2-3 times a day. I've been researching transitioning her kibble out for freeze dried/air dried food and then eventually to raw. I've read you're supposed to gradualy introduce new foods in over an 8 day span. Now my concern is since she's not eating kibble, how do I transition her food and get her to go back to eating and drinking normal??

hello and welcome
How long has she been getting the prednisolone (pred), and how was her appetite before? My first case of insulinoma was discovered in a ferret I had "rescued" only 2 weeks before because I noticed he suddenly stopped eating and had lost weight. If you just started the pred, it may take a couple days but no more to see increase in appetite.
It wouldn't hurt to try just giving raw now. Some ferrets go for it right away. I started by grinding kibble and mixing with water and ground turkey or chicken and never had any ferts reject it on the first taste.
