It seems like the smaller the subject is for the camera, the more skill and patience it takes. These little antelope ground squirrels (and I mean little, no more than 6 inches) would scamper about like big mice, only to sit still for a second or two.
Just when you get the lens pointed in their general direction, they were off again, like a woman late for a shoe sale.. You had no idea which way they would turn and run either. At least you know where the shoe department is.
