Charlene, Some ferrets can and will start slowing down at age 3. Others may start later but it is not uncommon at this age. You say your vet gave her a clean bill of health - did he/she draw blood for a panel and CBC? I had a ferret slow down at age 2...he's had several panels done (he's 4 now) and a splenectomy, and seems to be doing better now (that happened when I switched his diet to Totally Ferret). I think the best thing to do is cover yourself by getting a panel and CBC done - if those are normal and your vet doesn't feel any organ enlargement, and the ferret is eating, acting, urinating/defecating ok, and everything else is normal, it just might be normal aging. If you blood work is normal, at the very least you have established a baseline for future panels - and have given yourself some peace of mind.
