Review on Vibrating Dog Collar for Small Dogs - Non-Shock Training with Remote - Fits Dogs Under 15 lbs - Vibration & Sound Only - 1,000 FT Range - Long Battery Life by Cara Dudas

After moving I had to buy one for each of my cats. They seemed to think that the new house had new rules. It got to the point that on one occasion we even talked about the need to move home. That changed the rules of the game! Doesn't harm them at all. We tested the buzz function on my wrist at the highest level. The remote works quite a distance even when I'm up and they're down. Within a few days, behavior changes 180 degrees. No more talk of moving! The only downside is that I have to charge it every 2-3 days, but it only takes about an hour to charge, so it's not a problem at all.
