The Random Cat will cost you 120 Facebook Credits (down from 150 last time), and the adult sells for 4500 coins. It becomes an adult in 3 days and requires food every 8 hours. There are currently 205 of these left. The Random Horse costs 102 Facebook Credits (down from 1200), sell for 3600 coins, becomes an adult in 7 days and requires food every 16 hours. There are 445 of these available as of this writing.
These animals act like Mystery Boxes except that you at least know what kind of animal you will get. The colors will be random though, so there will still be a pretty big surprise coming at a pretty big price.
Were you lucky enough to score one of these? What kind of cat or horse did you get?
