That’s nuts

It took balls to draw this.

God I had a cat who did this he always looked like a dingus dragging a small blanket underneath himself as though he murdered it.

It is an important detail. Someone not familiar with feline anatomy might wonder whether straddling prey and dragging it in such a way interferes with the feline’s testicles. Clearly not a problem

Maybe they were working from a reference photo that had the balls be visible, and they felt it’d be weirder to not include them
