Yes, your little one can hurt herself from falling or jumping off a high place. Speedy injured her back about 3 weeks ago. She has one compressed disc. She has no real use of her back legs and cannot control bladder or bowels. She is currently on Pediapred, which we are now weaning her off of and Arnica (herb). I just added the Arnica in hopes that it will help during the physical rehab process. I also use a diaper rash creme to help with the urine irritation. I have to express Speedy's bladder as she cannot do it herself and when it fills up it just dribbles out. Speedy is in pretty good spirits, a bit of pain - to be expected at this point and hopefully a sign of healing as for two weeks she was in no pain at all, eats well and gets around from bed to bed. Speedy is about 7 years old. As far as I can determine she fell off the top of a Midwest cat condo and below that was another cage that she must have landed wrong on. The remedy - place a hammock on that outside of the cage so if they fall they land in the cage. The bottom cage can be used to run a rod up to connect the hammock on one side, the other side of the hammock is connected to a U staple on the wall and the other two sides directly onto the Midwest cage. The other side of the Midwest cage already had a hammock between it and another cage. My ferrets are free-roam but have cages to go into if they want to. I've had the Midwest cage for several years and this is the first time there has been a problem. Just goes to show you can never be too cautious when it comes to ferrets. Hugs to all. tle [Posted in FML issue 2201]
