I think I remember JT telling me about the gopher repelling gadgetry last year, and that it actually worked a bit. I had no idea one failed you, lol, just like the cats!
It's cool in a way as your cats must be of the loving kind. My felines are probably like the rest of the animals on the homestead, weird, slightly savage, and prone to displays of violence! Just in the last twenty-four hours there has been a steer dragging of a human, an escaped horsecapade, and I am sure more antics that I have yet to learn of;)
The primary displays of animal violence around here are Annie and Ulysses picking on Clarence.
