Newly diagnosed cat in my local shelter.

This is Harry. My local shelter just posted on Facebook that he was recently diagnosed with diabetes. I don't know details on what insulin, food, or meds he takes.
If you're interested here's the Petfinder link. It hasn't been updated to include his "special needs".
