Thanks for all the replies.
We talked about it and decided to stay with the old stand by, me cleaning the box.......lol
My husband keeps the dog business picked up outside so the cat box is my duty.
If we bought one we would have to move it so it could be plugged in. It is in the laundry room now. And we would have to run a extension cord up and over the door to get to a plug. Something we don't want to do. Moving it to the garage is a no go. We put the dogs in there when it is storming outside or during the winter when it is to cold for them to be outside.
She may or may not like the noise.
She may never use it and I would have to return it for a refund. (the store is 25 miles away)
