Cinderblock's first time on the treadmill trying to lose weight

Cinder was my late grandfather's cat until earlier this year. He was in poor health at 93 years old and Cinder took full advantage, gaining quite a bit of weight (as you can see!). My aunt took cinder in when my grandfather passed and had some success with diets, but ultimately decided to relinquish her to the experts in the interest of cinders health. We always called her "meatball" but cinderblock is definitely more clever! We can't believe she's blowing up on the internet now, but I'm sure my grandpa would be happy she's bringing joy to so many people!
