New entertainment right there. The goat roping business would go bust. Reduced cost for stock contractors and you could haul them in VW. My sister and I used to team rope a friends house cat that my mom took care of for about 6 months when we were kids. Not sure if we could have practiced on a rat though.
I don't think I could get my ole grey horse close enough to rope one of them, speaking of roping we were at an arena not long ago and someone brought in a load of miniature donkeys to rope, those little devils can flat run.
Good luck
