I wonder if you supplied tasty food at the end of a short trip if you couldn't train a cat to reliably follow the spot!!! Trip lengths could get longer with time. Always ending in desirable food! Add a remote video cam and we have an awesome steerable cat-cam or cat powered drone! She could greet strangers at the door to find out who they are. Or get inside a house to see if there is anything worth stealing! Yea baby!
