Petmate is the one I have. I used to have the Drinkwell but I like the Petmate better.
I haven't gotten my kitties anything yet. They are so spoiled that they have almost everything, (honestly) I get them toys all the time, treats constantly, and cat trees once a year. Maybe they will get a cat tree for xmas this year.
Or better yet, maybe I'll donate the money to the shelter and just give my kitties lovin's instead.
