The Gorillarium at Howletts Zoo, near the cathedral city of Canterbury in the southern English county of Kent, is about as good as it gets. If you are a captive gorilla. Or if you want to see one.

While many zoos feed their gorillas with a sort of innocuous cattle cake -- nutritious but hardly Jamie Oliver -- the gorillas here enjoy a diet of at least 150 different foodstuffs. Fresh strawberries in season, ripe mangoes, paw paws, nuts, fresh celery, herbs -- you care to name it, and they probably get it. A balanced diet par excellence!

They also have plenty of grubs, beetles, harvest mites, ticks and other creepy-crawlies. That is because none of the zoo keepers bother cleaning the Gorillarium floor on a daily basis. In fact, they only get around to changing the oat straw once every two or three years.
