Taking care of a few outdoor cats, and with winter coming where I live, there is a serious risk of frozen critter.   I purchased this cool, bigger sized house for them.  They already love it!  Took about 7 minutes to put together, probably because i was drinking a glass of wine, or it would have been quicker.  The house is rigid enough one likes to sit on the top as a lookout.  Very cosy.  One less thing to stress over!
