Cystic Kidneys in Ferrets


Ferrets are usually aged between 2-3 years old when this condition is first diagnosed, however it can be found in kits soon after weaning which makes vets think it could be an inherited condition. [wp_ad_camp_2]

Cystic kidneys are caused when large bubbles of fluid form and kill off the kidney’s normal structure when they continue to enlarge.

If only one kidney is affected, then it can be removed and the ferret will be able to continue living normally.

However if both kidneys are affected, the ferret will die when there’s not enough of the normal tissue left to keep the kidneys functioning properly.

Some symptoms to look out for …

weight loss
decreased appetite
increased thirst
increased piddling
dark sticky poop containing partly digested blood
