Harry's got the same playful streak as his brother Ron: curious, quick to pounce, and always investigating something new. He's been through a bit already and come out the other side just fine, a survivor from day one.
He's finishing up a short course of eye drops right now. His third eyelid had gotten stuck to the others, and it was clipped when he was neutered. He's on drops for about a week, and it has no effect on his vision. His eye may end up looking a little different from the other, a small scar from the whole ordeal, but it's already improving.
Once the drops wrap up, he's all kitten: playful, fun, and ready for whatever comes next. He's Hermione's son and Ron's brother, ready to graduate and join your family (unless you want his brother too).
