"Interestingly, in cats (other nocturnal animals), cutaneous 7-dehydrocholesterol 7-reductase activity (converting 7-dehydrocholesterol into cholesterol) was shown to be so high that the 7-dehydrocholesterol levels in the skin were insufficient to allow vitamin D3 photosynthesis [28]. Therefore, cats depend on their diet for their vitamin D supply (making vitamin D a true vitamin in these animals)".
