Review on Rechargeable Shock Collar for Small Dogs & Cats: Effective Remote Training Collar with Waterproof Design and 1000Ft Range by Buffy Nystrom

I got this collar because my cat is overwhelmed with grooming and the sound of her tongue spanking all the hairballs and tidying up finally got to me came. Most of the time it works well, the vibration strength on level 3 is enough to distract her from over grooming. The battery life is also very good as it can last for several days on a single charge. (Each night before bed, I remove the collar and turn off the power). However, there is one fatal flaw that sometimes renders the product unusable. The sleep mode feature is a TERRIBLE idea. Cats often move very slowly, which is why the collar does not turn on even with a slight vibration. Not only that, there have been instances where the cat would walk around and the collar would not turn on and I had to grab the collar with my hand and squeeze for a few seconds before it would turn on again. I would give this product five stars if it wasn't for the crazy sleep mode feature.
