Cat Canyon has really been quite a mystery. No plans have been released or even hinted about. However, the plans for the African Savannah call for a new cheetah exhibit, which would mean that the cheetahs would be leaving their grotto in Tiger Canyon. So perhaps Cat Canyon will not open until 2013 because they are waiting for another phase of the African Savannah to open first. When I was at the zoo about a month ago, there was construction/destruction going on where the African Savannah will be located.
