the ONLY AAFCO approved supplement of Vitamin K in cat foods is the supplement Menadione Sodium Bisulfite Complex
As for the toxicity concerns, there are no reports of nutritional toxicity of any vitamin K sources in dogs or cats readily available in the literature, and certainly no descriptions that could be found showing vitamin K3 (menadione) was harmful to dogs, cats or other domestic animals. The recentNutrient Requirements of Dogs and Cats (NRC, 2006) and the Vitamin Tolerances of Animals(1987) texts are authoritative reviews on the topic, and they state that toxicity of menadione by nutritional routes is in excess of 1,000 times the requirement. Further, vitamin K3 has been fed to poultry, swine and companion animals for more than 50 years without incident. So, nutritional supplementation with vitamin K3 doesn't appear to be a smoking gun.
