fruits (and vegy's) as treats are a big no-no for ferres!! blockages are an issue as is the fact that they can't digest the stuff anyhoo, so, why bother?
now, if it's just been banana, and mushed, that's not so bad from a blockage point. actually, banana and pumpkin are used to help move blockages through the system, so, all in all, not all that bad. if she's been giving apple pieces (or some other hard fruit) too, that's a whole other story! and may still be an issue and you'll need to have a talk with mom to find out just what she has been giving the ferrets!! go back a whole year, too. any hard fruits could be stuck and sometimes things get stuck and then come loose again, so, this could still be a blockage issue - even from something given a year ago! i'd have the vet take a look at the little one, too, to rule a blockage out.
how old is the ferret?? at/over age 3 then insulinoma might be the problem - maybe even if it's younger if fruits have been a steady part of the diet.
for insulinoma crashes, rub a dab of the clear karo syrup (size of a pea) on the gums. wait 10-15 minutes for the ferret to start responding and then feed a high protein meal. pure maple syrup can also be used. basically any kind of syrup as long as it doesn't have flavorings in it.
other signs of insulinoma are: lethargy (sleeping a lot, speed-bump a lot, not playful), losing weight even though eating, staring off into space in a daze, glassy-look to eyes and/or have that squinty look to them, drooling, excessive licking-the-chops, runny poo, walking funny - back legs weak, stumbling, walking off to the side or in circles. edit: shivering is also a symptom.
if the ferret is showing any of these signs, then you need to get it to the vet for a check of the blood glucose level. under 80 is borderline; under 70 is definite for insulinoma. treatment is easy enough with meds and some dietary changes.
prednisolone given 2x daily and modify the diet to remove grains. all if you can and if that's not workable, then move to a kibble with less grains (and definitely NO corn) in it. and supplement the diet with high-protein meals - homemade gravy or soupies at least 2x a day. the pred should be given with food (it's hard on the stomach), so, i do it the easy way and mix the meds with the gravy. they get the food in their tummy to protect it and the meds (which taste a bit nasty) aren't as obvious and it's not a fight to get it into them.
tell mom 'no more fruit for the ferrets'!!!!!
