Thanks Arizona Docent - I am sure that is the right date, thanks for the clarification. I wish I had kept my shirt that they sold, which raised several thousand dollars - it was a feline cat with fishnet stocking, smoking and laying on a bed/couch with the saying "support your local cat house" It was great, but I lost my only one.
So I will now change my job listing to June of 1985 opening.
Shirt seems a bit risque' for a family attraction like a zoo.
Incidentally, the Exotic Feline Breeding Compound has used that phrase for years (support your local cathouse) and has shirts with it, but they just have the phrase with no picture.
