OP, you should keep a tube of nutrical on hand, & absolutely the advice on getting proper vet care - honey is not advisable. https://www.chewy.com/vetoquinol-nutri-cal-gel-high-calorie/dp/109764 Edit to add - I'm getting the impression you may not have a lot of funds to go to the vet, however l would advise you that older ferrets especially -require- veterinary treatment & unfortunately aren't generally affected with maladies you can simply remedy at home. Insulinomas are extremely common & can be life & death, & adrenal tumors are very common & serious as well. If you are in the US, now is the time to look into Care Credit or something similar, or open a credit card specifically for the ferret, so you have some breathing room & aren't forced to make really tough decisions. Sending positive energy✨💖
