In 20 years we've never seen a ferret get that close to death and turn around. The only thing we can figure out is that she apparently has a very negative sensitivity to Lasix. Talk about unusual. We've never had one do this with this med. There were times yesterday when she lost consciousness, times when she was barely breathing, times when her breath was chilly feeling, etc. The others ferrets first were afraid around her, then decided to cuddle her, then reached the point where they were again very afraid and nervous. The odor she had was terrible but around 4 a.m. it changed with a slight undertone of her regular sleep smell. During the wee hours, though, she stopped having any purple to her rear feet, and her body stopped being so chilly. At around 8 a.m. she was clearly back with the living, and at 10:30 she decided to drink on her own. She's been getting flat pick guitar music, lots of attention, much sleeping on us, and we are doing her care in shifts so that someone is always awake and with her which means we are very tired. We are waiting to hear from her vet and I guess we'll likely be finding a home for some Lasix. I somehow doubt we'll even be trying the Ovaban; she was already terminal and surviving beyond the time anyone expected by pulling out all stops, now her individual quirk that set off her collapse has likely done further damage but no one had any reason to anticipate this. That's one of the things we all have to just try to remember, no individual of any species is going to be text book in everything; all have their own individual quirks and some of those quirks are whoppers. Figured that you'd want to know that this one collapses with Lasix and recovers mostly about 36 hours after it is stopped. Normally, it would have been a very good med for her to have, but this is just her. [Posted in FML issue 3822]
