My babies (2 cats and 2 small dogs) love it! Especially my cat Charlie who was recently diagnosed with diabetes.
I really like the little fountain. My roommate and I each got one, the green and purple respectively. The purple is a hint bluish, but preferred to the aqua colour. I don't use the spouts because one of my cats has whisker sensitivity. The water stays cleaner; there was some hair in the filter space as to be expected, rinsed out with the spray function of the kitchen faucet.
The fountain is small but perfect for cats (2/3 picky cats approved) I wish they made a bigger one more suitable for medium to large dogs. I'd give the fountain itself 4.5 stars so far simply due to size capacity but Petlibro's customer support was on it when assisting me with some concerns about my order and promptly helped to resolve the issue. So 5 stars over here (: please make a bigger one for my dogs!
Cats love the fountain, it is very quiet, and easy to assemble/disassemble. My only issue is that both filters are to be replaced every two weeks. It’s wasteful, and honestly there has to be a reusable option for at least one of the filters. I can understand more care needed as these little guys are drinking directly from it, but I know there’s room to improve.
