Tiger Cage Escape

You're a janitor at the zoo and your night-shift couldn't be going any worse. You just locked yourself in the tiger cage. Lucky for you the tigers are currently in their outside habitat. You must first shut off the power to the cages electronic lock to free yourself from the cage. Then you must find the hidden emergency access card that you overheard the veterinarians talk about to get out of the tiger holding room. You have 60 minutes before their scheduled nightly feeding, in which the outside door will automatically open for them to come in and feed.
