They enjoy spoiling their pets. What they don't realize is that animals are wired to eat whatever is available, because in a natural world, they would have to put out a lot of effort just getting enough. The result of overfeeding can be deadly, as a pet packs on pounds that interfere with their activities and can result in diabetes, heart problems, and organ failure. The subreddit <a href="https://www.reddit.com/r/dechonkers" alt="dechonkers" class="on">dechonkers</a> follows the diets and progress of obese pets that are making their way back to a healthy lifestyle. And it's not just dogs. Below you'll see two pictures of a cat named Skinny.

Bored Panda posted <a href="https://www.boredpanda.com/pets-losing-weight-before-after/">before-and-after pictures of 30 former chonks</a> that display amazing progress in their quest to get healthy.
