Hi everyone. I just wanted to let you know the great news. Storm's biopsy came back normal!!! He's doing excellent and seems to be a much happier and content cat. I'm sure he feels so much better now. In a few weeks I'm going to start brushing his teeth at least 2 times a week as well as my other cats. Hopefully this will help everyone's teeth and gums. Thanks again for all of the emotional support.
