1) Do any of you use one?
My mom uses the Littermaid for her cat. I use....'hand held sweeping action'
2) If so, which brand and where did you get it?
Littermaid...Ebay for the first one...it broke when my brother took the cat and dog ...so he bought a new one. You can find them at Petsmart...petco...Walmapart, Target...etc. Petsmart has other types of automated things too...they dont even look like they work that well though.
3) Also, how much did you pay for it?
65 bucks on ebay.
4) One last question, do they actually work?
Oh yeah...my mom loves it. Id get one in a heartbeat if I could. READ their directions when it comes to getting your cat accustumed to the new machine because....it can scare the HELLO out of a cat.
