At the Animal Playground. The foxes appear at the Night Safari's Creatures of the Night Show but are otherwise kept off-exhibit. The only chance to see them in the daytime is if they make an appearance at the Animal Playground. There is no schedule of animal appearances at the playground, so it's down to luck what you might spot.
Random list of other animals WRS have that are off-display and only visible in shows
A lot of the raptors at Jurong
Raccoons
North American beavers
Some animals that are housed in the other parks appear in some of the shows, for example servals in the night safari show and hog badgers in the rainforest show
@noobmaster69 there’s also that one Indian Sand Boa that’s been around forever that you can only see during the show at the zoo, and the River Safari show has Southern Oriental Pied Hornbills too (otherwise only seen in Jurong).
oh and all the domestics that you can only catch at the farm area (ferrets, hedgehogs, dogs and cats)
