Nope. I don't like using long acting pred, I like to be able to
tweak the dose if need be.

What about Proglycem? It's already proven to work in ferrets, and
it doesn't have the same side effects.

No question from me, though I find having a younger ferret in the
household keeps the activity level up and the rate of weight gain
down. Not every one can get there pred-belly ferret a pal, however
;-)

See above.

I don't do surgery on heart cases - call me paranoid, but I'd
rather have a live fat ferret than a dead one on the table.

It also makes them hungry, so they tend to eat more. I usually
counter this by decreasing the caloric level of the food (change to
senior diets, use lean chicken baby food, etc).
Hope this helps,
