Listen here, kid, this ain't funny, it's just messed up. So, basically, a dog and a cat meet, and the 'joke' is that they just start having sex right then and there. I know you ain't the sharpest tool in the shed because you think this is funny, but animals can't consent. And 'no cap' means 'no lie.'
