Hide the Pets
Animals shouldn't live in houses. Well, that seems to be the mantra of the real estate industry. If you own one of those slobbering, hairy pests -- that loves you unconditionally, protects you vigilantly, amuses you with its absurdities and never judges you for your failings -- hide it. That way, you won't have to explain how you managed to get all the hair out of the air conditioning ducts (because you didn't) or managed to suck the pet dander out of the carpeting (never happened).
