Bought the heated multiple cat “outdoor” house for my indoor cats who want to use the screen porch year round. They loved it from the moment that I put it out. It’s a great product for my cats’ needs.  But, it could be better.  Here’s how:
   1.  Longer cord.  5-1/2’ is NOT long enough. (I added a 20’ outdoor extension with waterproof connector. Now it goes to the cats’ favorite spots).  This should be a minimum 10’
   2.  Larger entry/exit.  My very tall cat is put off by the 9” tall doorway. 

Really, only 2 issues is a triumph.  I do recommend this item
