50 Chonky Cats That Underwent Incredible Transformations To Become Healthier Kitties

It doesn’t take a genius to understand that, despite the cuteness, pets shouldn’t really be overweight. So here is a collection of before and after pics of cats whose owners did their best to help them lose weight.

#2 Adopted A Chunk And Now He’s Shrunk

It’s not hard to see how some of these cats ended up in this situation. Just like us, cats have evolved to be out in the wild, finding food, perhaps chasing it and fighting. Instead, we all sit inside comfy, climate-controlled homes and have regular meals that are pretty calorie-dense.

Plus, who doesn’t like a little snack? Most of us probably eat more than we should and move a lot more than we do. A housecat doesn’t exactly have access to the same physical activities that it would have in the wild. And since most of us love our pets, we always like to give them a little snack to munch on.

So experts have a number of tips to help get your cat’s health back on track. First and foremost, a food scale can be useful to understand just how much (or little) food they are getting. There is no one-size-fits-all scenario, as everything from the cat’s breed, gender and access to the outdoors will influence how much it needs to eat.

Of course, a healthy lifestyle isn’t just eating less, it also involves more movement. While for humans this tends to manifest as a gym or at least more walking, it can be a tad harder to implement these changes for a cat. Getting a cat to use a treadmill is not going to work in most cases and the majority of indoor cats are going to remain indoor cats.

So the onus of responsibility will fall upon the owner. The best bet is to get a few toys and see what the particular cat likes. Then have a few minutes of play sessions every day. Not only will this make the cat more active, but it’s good stimulation for its brain and it helps create a bond between the cat and the owner.

Additionally, it can help to introduce some more ways the cat can be active even when the owner is not around. Vertical spaces are a great option, particularly if the cat has to jump and climb its way up. Our feline buddies do like a height advantage, so this way savvy owners can “trick ” their pets into exercising more.

As cute as we might find these chonkers, it’s not just their hearts that might be at risk when cats are overweight.

On top of that, they may suffer from my joint issues and have general mobility problems. This can create a sort of vicious cycle, where the cat doesn’t want to move, gains weight, and struggles to move even more. This is why it’s vital that the owners take preventative measures, or at least do their best to play with their cat regularly. If you don’t like playing with a cat but still own one, perhaps rethink your life choices.
