When is the last day the zoo is open and if i came would all the animals be out

I believe October 27th is the last day and if I'm not mistaken all of the animals will be out. They will have a Halloween zoo thing going.

Some animals that are more accustomed to warmer climates will be put into their shelters till next summer when the heat reaches the proper amount as with any zoo last year most of the animals had been moved to their shelters by the Halloween event.
