My brother has 35 cats and does not run a rescue or claim to. He might be considered a hoarder but his house it clean, neat and organized. No odor of cat as you walk in the door. He buys kitty litter and food in bulk (Sam's Club). Sometimes it is hard to believe he has all those cats since you only see maybe 5-6 at any given time (unless it is feeding time). The longer you visit, the more cats you will see but rarely than just a few at any given time. He is single, would rather stay home than go out and the cats are the center of his life (I have ONE cat by the way). I have seen people that have just a couple of cats and their house reeks.
