I had high hopes for this littler box however it didn't play out as I hoped. The box was fairly simple to put together,  but I quickly realized it's SMALLLLLLL none of my cats or my moms cats will fit in there. If you are using it for kittens or an adult who is under 6# the will fit fine.
I had a lot of difficulty trying to connect the box to wifi and my phone, the instructions did not explain how to do this very well.
