They won't worry if she doesn't eat one day, but if her food is untouched for a few days, they'd consult one of the Zoo's veterinarians. Before moving the cats into exhibits, keepers walk through the yards to clean up yesterday's feces and any debris. Despite the popular perception, keepers do not enter the enclosures while the cats are in them. They're used to a routine, but that's not the same thing as being a pet. Keepers can maneuver the cats to any yard with a color-coordinated pulley system, another safety device.
Doors leading into the runway are blue, so the corresponding handle is blue.
Doors within the runway, which keepers use to keep cats apart while indoors, are color-coded yellow. Once the cats are in the exhibits, the grunt work begins. Keepers hose and scrub the floors of the indoor enclosures and prepare the cats' dinners by defrosting ground meat and weighing portions. The cats are on a diet designed by the staff at the Toronto Zoo, but the amount of meat they are given depends on their weight and is determined by the Zoo's veterinary staff. The cats are fed only indoors and keepers serve them through a food shoot, similar to a mailbox, so there is no hand contact with the hungry cats.
