Hooray! Another Cats On Tuesday!
I've been delving into cat food issues recently. It's a fascinating topic. For example, there are the stories about rendering plants putting road kill and euthenised pets into pet food as well as dozens of other products. And there are the periodic scandals about pet food that isn't quite what the label says it is.
Traditional all fish or all liver cat diets also come with problems.
Cats that eat too much fish can suffer from taurine deficiency and lose their eyesight. Too much fish can also lead to Vitamin E deficiency and cause a killer condition called steatitis or yellow fat disease.
Cats who eat too much liver can overdose on vitamin A. However, this study from the cat diet researchers at the University of California point out that cats are unusual in that even a diet heavy in liver for 3 years doesn't lead to the sort of toxicity you'd expect from other mammals.
But the most interesting thing I've read in a while is a study sponsored by Hill's pet food that shows that urinary tract problems are associated with cats who eat too many dry foods. The researchers recommended wet food is much better for kitties.
A pal whose kitty has these problems tried using apple cider vinegar to cure her pet. But when I spoke to a vet about this she said she has not heard of any scientific studies. Also, the vet thinks it could work IF the problem is caused by urine that's too alkaline. BUT as problems can also be caused by urine that's to acidic, apple cider vinegar could also make matters worse in some cases.
Well, I'm going to keep on reading. Also, a Katz Tales piece about this issue will be out in the Star this or next Saturday. Sorry I can't be more specific, with the change in economy everything is a little upside down.
And in case any of you are into this subject, here are some awesome links:

Check out what other animals must eat meat to live. There are a lot of obligate carnivores around, including tigers, crocodiles, civets, and hawks. Although penguins and all ocean mammals eat mostly fish, they too are classed in this group.

The Carnivore Connection to Nutrition in Cats
Idiosyncratic nutrient requirements of cats appear to be diet-induced evolutionary adaptations
Excellent studies of what cats need in terms of nutrition but as these are scientific papers they are rather technical. Worth going through though!
