All I know is when we had Zoee fixed we only kept her collar on her when we could not watch her, like while we were sleeping or not home. Luckily Bruce works from home, so she didn't have to have it on ALL the time. But she was pretty good about not bothering it. Which was surprising since when we first got her she would always "clean" herself after coming in from a potty break.
Do you think you could leave the collar off if you are home with him, and just make sure he doesn't bother it?
