I was so excited to get this cat house! There are a few feral kitties that like to hang around outside my building and I always feel so bad for them in the winter. This is nice and sturdy with a sleek water proof covering. There are open flaps on each side so they never feel cornered and the heated pad gets nice and warm, but not to the point where Im concerned about leaving it on. Even the set up was incredibly easy! One of the sides Velcros  to the bottom to create a seal but can easily be opened up to clean when needed. The cats are going to love it!
