Why is that some people are allergic to peanuts and some aren't? A peanut is a natural food therefore it's okay for everyone right? The reason why some people are allergic to peanuts, although, processed in nature is 'cause of the individual metabolic response. The same theory is applied to both cats and dogs. Although all of our medication and supplements are made of 100% natural ingredients researched and developed by holistic veterinarians, each pet has an individual metabolic response. This is why it is important before starting or adding a new medication to consult with a certified veterinarian.
