Well, it depends on the species too. Ralts - her first for - are especially sensitive to emotions. If you picked up another species, I'm sure it would be fine. And I have some... unexpected 'therapy' animals.

My Arbok, which is a massive snake larger than myself, seems to think he's a dog or something with the way he puts his head in my lap, for example. But Nekomata, my Espurr and my only other Psychic type is still a baby, so I haven't had much of a chance to train her yet. I'm sure she'll grow to be something along those lines, though. I train my team every day, but I'm not into the hardcore battling that other people are. I'm a Breeder, not a Trainer.
