booda cleanstep Litter tray?

It looks really nifty but it also has some major downfalls that kept me from purchasing it, here is a short list why I didn't get it.

It traps odors which is good for humans but horrible for cats.

Not being able to see inside causes humans to forget to clean it out.

Cats like to see outside while they are doing their thing in case of ambush.

It looks very small and chances are if used a lot eventually a cat will step into its own doing.

No room for proper back arching.

Way tooo expensive for my pocket book.

This is what I did for a great cheap solution http://www.amazon.com/Clevercat-Top-Entry-Litter-B...

you can make your own witch is what I did, keeping the cost under 6 dollars the regular cost of an open litter box

Best of luck
