Since this thread started I have observed Ellery paying attention to a lot more than just animals on television.

Last night he was on my lap while I was watching a nature program showing people walking around lawns and groves of trees.

I couldn't see Ellery's eyes, because he was facing away from me, but from his body tension he was obviously involved. And then when a collie showed up onscreen Ellery didn't move or make a sound but his ears flicked.

Another program showed lions, both at rest and walking. Ellery bolted upright, watching intently.

I've gotta get that dog some videos.
