This source indicates an 38,000 km apogee, which is is about 1/10 the distance to the moon, and just barely beyond geostationary.

I haven't seen the orbital parameters of the X-37, so it may be in an elliptical orbit for some other reason, such as spying on or interfering with geostationary satellites or who knows what else.
They can't figure out obstacles very well if they can see where they want to go, but are impeded. They just pace back and forth, frustrated, instead of walking around the obstacle.
They are very social, recognize people, and can be trained in some limited ways (eg. to return to the coop with whistles, if you associate it with treats).
