Hey y'all! I joined this forum in hopes that I could get some insight. This is going to be weird to hear but I do not have a Besenji. I actually have 2 Maine Coon cats that have Fanconis. I've done enough research to know that Besenjis, in particular, are affected by this disease. Cats are not supposed to get it, although I have 2 that proves everybody wrong. We have been dealing-feeding a NO protein food because their kidneys cannot handle protein and supplementing potassium 2x a day every day. If anybody out there has had to deal with this, can you please offer some insight on how quickly the disease progresses, as they age does it get worse, etc…I realize it may be different for cats but I'm just trying to get all the info I can right now. Thank you!
