Why would you make your cats' water supply depend on such a complex system, when you could just use gravity?
Search gravity water bowl for a cheap one to leave near your existing fountain, or https://www.amazon.com/PetSafe-Drinkwell-Platinum-Fountain-Drinking/dp/B000L3XYZ4 for a gravity-fed electric fountain.
EDIT: sorry, I misread "our cats wouldn't have been without water"
My boyfriend bought this for my kitten for his place. Despite my reservations on the plastic material and hard to clean areas it’s performed well and myself and the cats love it. Not as hard to clean as I feared.
Before making a purchase ask yourself if your cats want more of a gurgle or a cascading stream
I used an automatic litter thing..problem was it was never big enough as they got older. i use these giant litter boxes and the XL sifting little liners. that is what i found works best. you're going to find out what they knock over when they just decide to fuck everything up. i use a fountain, but they also love having a water bowl. I fed my kittens only raw meat when they were younger. ended up going to dry food just because it was easier but I think they really liked having it as a kitten. use 1 room initially. assuming you get it at 2 months old. if not, try to section off a floor or something. they can be in furniture out in the open it doesn't matter once they get a little older. keep it simple at first. bengals are super smart.
when mine were kittens i used bowls but occasionally sprinkled food around the floor to help them development the skills to smell around and track their food.

Nope, not at all. We have the Drinkwell Platinum.
