Definitely, Stephanie, not directed at you. It was just something I have read about cat foods having too high levels of some vitamins, especially vitamin D, so that if people supplement, they are just adding to the problem. Especially in Sierra's case, when she eats so little at times, that is a case when you would want to supplement, because she may not be getting a day's full serving of food and thus not the correct amount of vitamins. I was just referring to normal healthy cats with healthy appetites. Sorry, I should have made myself clear.
Interesting, Pat. I did know about the linoleic acid thingy, but never thought about why the flax seed oil was put in cat foods. Another thing along the same lines is when they supplement with beta carotene for a source of vitamin A, when cats, unlike people, cannot convert beta carotene into vitamin A. But they know flax seed oil and beta carotene are popular human supplements so they add them to make people think they are on the cutting edge of cat nutrition when they are anything but. Becky
