There are a few people that have made the comments that if Small Cats were just added into the Big Cats that they would be up to level 30 with in 2 weeks. This is simply IMPOSSIBLE.  Those that have been with us and have seen a new species released can attest to this a Lion had to work its way up to a level even if it was crossbred to get traits from a higher leveled animal say Tiger or Jaguar. The out come that would happen if you combine a Leopard level 3 and a Jaguar Level 28 you cub would be either a Leopard 2, 3, or 4 level or a Jaguar level 27, 28, 29. Level is again tied to the Species which is currently tied to Fur.
