I saw this, and I actually like this. It self-cleans, it attracts cats to come back to drink, you can monitor how much its drinking (especially good for cats who don't drink enough).
The only think I am skeptical its that it's plastic, though BPA free and no filter.
What do you all think? Would you buy it when it comes on the market?
(I posted in Cats Meow for discussion as its not out on the market yet)
