The bigger question to me, in regards to the cat house, is "WHY on earth would we want or need to store cats??". If I have a cat on my farm, it's for decoration. The cats have no productive benefit like the pigs, sheep, goats, cows, horses, etc have....so it boggles the mind to think anyone would have that many cats on their farm that they have to hide them in a cat house.
Maybe we're going to be getting Persians or Angora cats so we can knit sweaters..??
