I washed him every 2 days, cleaned his bedding, and box daily. However he never learned to use the box. I spent months working with him on it and instead he would rather just dig out all the litter, and sleep in the box. And poop in the litter pile he made on the ground lol. His biggest issue was that he peed on his head. -_- not to mention he was white, and no amount of bathing got the yellow off his head. I love the guy to bits, I tried to find some photos of him but im not sure where I have the stored. I definitely should have went with a female ferret though.
