That third picture makes him look like he became possessed by some demonic entity if there is such a thing as that.

Very dark eyes...

Looking healthy and pudgy though.

I have a few of my own, sometimes i purposely not feed them so they do not lose their insticts on finding their own food. If you give them everything they will become very lazy. And I find that unhealthy to their psychological state.

Same goes with dogs sorta. Street dogs are very good at finding their own food, unless they have been conditioned not to find food for themselves.
