More than half of cats and dogs are overweight. This not only makes them less active, but it can also cause lots of health issues and diseases. But there’s hope! Even if a pet is already overweight this situation can be changed.

And we at Bright Side collected some great examples of animals that amazed us with their transformation. They didn’t keep waiting for the right moment to come and with the help of their owners, they achieved some incredible results.

1. ” I adopted her as a very chunky kitty and this has been a process for years.”

3. “Adopted this cute and (very) overweight kitty a few years ago, put him on a diet, and now he’s less than half the weight of when I first got him!”
