I use this to chase cats away from my yard, or rather, the owners of said cats know not to let their cats loose in our neighborhood unattended. It turns out that there are ordinances in my city against indecent exposure, so I do need to wear a banana hammock while using this product outside of my home. I also think that the initial impression of a 280# man bearing down on an animal at top speed, mewling and slobbering, with a slab of silicone dangling from his mouth may initially be off-putting for some cats. But, once I have wrestled them to the ground and the clawing and biting has subsided, I can begin licking the cat until its horrified owner returns home from work to ask what I am doing. Obviously, the cat was on my property, and I can lick anything that I want on my property. Plus, I am using protection, as this silicone barrier prevents the spread of disease. I'm often told, "Well, that's MY cat!" To which I say, "Then get your own Licki brush, because this is obviously the reason that YOUR cat keeps wandering onto MY lawn." I rarely see the cat again. In fact, my neighbors make a conscious effort to avoid eye contact, which is an added bonus.
