I don't have the heart to treat animals badly, especially those that are mine (like my Cat). With that said, I would probably treat my Pokemon with a whole lot of love and care. I might be a little strict with it comes to training, but in the end I'll give them a hug or cuddle them if they've done well, much like what I do with my cat in real life. Hell, I might even baby-talk to them if they're a younger Pokemon, such as a Baby Eevee or something and perhaps even act all motherly.
