Does your cat love drinking out of the sink! Then buy this bowl. It arrived a day later than estimated. Not a biggie. Very easy assembly. Theres no line to say how far to fill the water. But add a little water to get the pump started, then turn it on, fill till it runs silent.  My cat thought it was a water park at first. But now the newness has worn off and he uses it with no problem. My only complaint is the power cord. It sticks far out from the wall. If you have a cord chewing cat, I wouldn’t try my luck. It would be a better design with a plug flush to the wall. Overall though great water dish.
