A new tiger enclosure being built at Noah's Ark Zoo Farm in Wraxall is just a month away from completion.

More than a dozen people have been working non-stop on the one-acre site since planning permission was granted in March.

Owners Anthony and Christina Bush are spending £200,000 to create a home for five endangered Bengal tigers, which could be at the zoo by next month.

It will have five dens, with bullet-proof glass windows for the public to peer through and tunnels for the animals to get from the dens to the enclosure.

Keepers and vets will also use the confined space to safely tranquillise and treat the huge cats. The enclosure will be sustainable, harvesting rain and underground water into underground storage tanks to replenish the two ponds. There will also be platforms for the tigers to jump on and bask in the sun, wooden structures for them to climb and scratch their claws on and, in time, a collection of trees.

A 16ft wire-mesh fence will keep the public and tigers apart, and viewing platforms will allow people to watch the tigers on their own platforms or as they play in the pools.

The tigers will have three keepers, two of whom are on a week's training course at Whipsnade Zoo, Bedfordshire.

Mr Bush said: "We are hoping the tigers will be here in mid-June, but it is dependent on the zoo inspectorate passing what we have done. For those who like big cats it will be pretty exciting."
