Yes and yes, and a bit more, in fact.

They're intelligent, for animals. The bunch I have Impressed on me when they hatched, so they're... linked to me, I guess you could say. They're able to let me know where they've been and what they've been doing, they can run simple errands for me as well as fetch things for me as long as it's small enough for them to carry. Things like that, mostly.

.... they're amazing. I've never seen horns like that!
