Convenient for my cat, by cons for small shaggy dogs, Lhasa Apso in my case, the hair and ears soak in water when they drink, you can imagine the state of my tile .... As for the cleaning required every 3 days because the bottom of bowl remains dirty, it's not easy, you have to take everything apart and if you do not have a large sink (in my case), flooding is still assured ... I am disappointed with my purchase, I would recommend to people with multiple cats 5L model because it is too big for only one cat, or for owners of small dogs with short hair.
