I have two cats - one slightly chunky but not too bad, but the other is fucking ripped. I mean properly shredded. You don’t mess with him, especially as he has huge claws.
My cat is like this. He legitimately beat up my uncles five chihuahua dogs. The vet called him fat until he went on the scale. Then said he's at an optimal weight. The cat scares my friends. It headbutted one on the leg and made him limp afterwards.
