Hi there! I read that menadione , found in many cat foods , can be toxic . Is this the same as manadione sodium bisulphate complex that's in my cats kibble ? Thank you

Yes, this is the same as menadione. I would not be too concerned about this ingredient though. Menadione is simply a synthetic form of Vitamin K. As with many topics surrounding nutrition, there has been quite a bit of misinformation and hype about manadione and it's potential for toxicity. This ingredient is an essential nutrient that is put in pet foods at small amounts to ensure the food is nutritionally balanced and is not known to be toxic. It has been shown to be toxic in laboratory animals at extremely high doses (more than could ever be attained from eating the food), which is not very remarkable, because everything is toxic at some point. This ingredient has been put in pet foods for many years and there is no evidence to show that is has any negative effects in small amounts over long periods of time. The concern that it is toxic at the amounts in pet foods is unfounded. I personally have no qualms feeding this to my pets.
For more information, I recommend you read the article at the link below.
