Link between fish-based foods and chronic kidney disease in domestic cats? — 2 Comments

  1. I read your article on the possible link between consumption of fish in the diet and feline chronic kidney disease. I had a cat die of that in 1998. My present cat loves fish and seafood. What caught my attention was the can in the photo accompanying the article. I recognized it despite the brand being obscured. I used to feed my cat that same brand and flavor a lot. I particlarly noticed that Scottish Wildcats are free of kidney disease. At his last check-up, my cat’s veterinarian told me that, unusually for an 18 year old cat, his kidneys were completely healthy like a very much younger cat. He loves fish and I feed him a lot of it. Other than smoked salmon-which he doesn’t like, he prefers fish to any other meal. He’s a Pixie-Bob and they are supposed to have a few Bobcat genes as one of the original cats from whom the line was bred was supposed to have been the product of an encounter between a domestic cat and a Bobcat, and I was wondering if possible that my cat’s kidneys were being protected by some genetic inheritance from Bobcats? I know Bobcats are not Scottish Wildcats, but Bobcats are comparatively long-lived for felids, and as far as I know, which is not very far, their longevity might possibly be due in part to a freedom from kidney disease akin to that enjoyed by Scottish Wildcats. I know Bobcats were not part of the study you were writing about, but given their relative longevity, perhaps some researcher in future might want to investigate if Bobcats have a similar immunity to this particular kidney disese.

    • That is an interesting thought about bobcat genes protecting your domestic cat from kidney disease. However, despite the fact that it is a well-reasoned argument I think that you will find that it is untrue because all the reports about the Pixie bob state that there are no wild cat genes in this purebred cat breed. They are selectively bred to look a bit like a bobcat but there has been no mating between bobcats and domestic cats in this instance.

      My guess is that your cat was particularly robust in respect of kidney disease. I’m going to guess that this individual cat had a genetic makeup which helped to protect them against kidney disease. Some purebred cats are predisposed to it and some aren’t. There is a variability there. Certainly, your experience flies in the face of the article that you refer to which states that there might be an increase in the possibility of contracting kidney disease if a cat eats more fish-based foods. That was, however, a very tenuous report it seems to me.
