I was thrilled when the drinking fountain arrived. Unfortunately, my cat eyed it with a lot of skepticism and then completely ignored it. I was pretty down. Such a, somewhat more expensive purchase, for nothing...
Then, after about 5 days, I observed how my tomcat drank more and more from the drinking fountain. Longer and more than usual. I actually thought my cat was well-supplied with liquids since he gets cat soups and wet food. Now I know, no, he would have needed a drinking fountain earlier.
One point deducted because the fountain is a bit too large for a cat. A smaller version would be very nice.
