Chiroptera - here's the deal, set up a video recorder, so when you go off to work or run errands and Royce knows you are gone...you can see what happens. Btw, we want to see what happens too! (lol) come on now, it will be like sharing a family video. I can't stop laughing (visions of him going for it, getting the vibration, slinging it out of his mouth...and the "deer in the headlights look?" What the heck did mom put on that pillow? Let's try again?! 'Cuz I am a teen and I don't give up that easily. With the vibration in his mouth, the freak out look, crap! I am NOT touching that thing again!!!)
Sorry, it was all a visual...I can't stop giggling.
You know, you can always try the lower setting first to see if it works. It's going to be in his mouth, which will conduct electricity better. If they walk on it their feet are sensitive but if they put their mouth on it, it's a little different.
Now he's a teen and probably because it won't hurt him and it will take him a couple of times to figure out it does not feel good in his mouth. It will save your chair...and you can send it to America's Funniest Home Video's for the $10,000. (j/k) that would give some idiot some idea that may hurt an animal and we don't want that.
