You ever see a cat play with a mouse at the barn
It's quite comical. Sort of what I'm doing to Trigger. 
No, I have never seen a cat play with a mouse.
It's been a long time since I spent much time at a barn.
It was a great going to see the Teagues when I owned a piece of WIJi. My WIJi horse shoe is somewhere in a box of crap :I brought back from Martha's Vineyard when I sold my property there. I have to dig that out.
I sat behind a horse once for a 1/2 mile lap a long time ago in Ontario.
Honestly, I don't care much for being close up to horses. Jerry Bailey would tell you he fells the same.
