Two of Werribee Open Range Zoo's cheetahs, Kaidi and Inkosana, were given routine health checks this week.

The seven-year-old brothers underwent a general examination by the zoo's senior veterinary team and also endoscopic tests by specialists from the Melbourne Veterinary Specialist Centre.

Initial results indicated the boys are in good health but vets now have to wait several days for results of multiple biopsies of their stomach, colon and small intestine.

The brothers have recovered well and have been moved to an off-display area for six weeks while their exhibit undergoes extensive renovations.

The new-look cheetah exhibit will be doubled in size and extensively modified to give it a greater ‘open range' feel with extended views to adjoining zoo grasslands where animals including oryx and camel roam freely.

Project Leader, Peter Sullivan, said the new exhibit would provide greater enrichment for Kaidi and Inkosana.

'The cheetah will now be able to view other animals across the grassy plains which is what they like to do in the wild,' Mr Sullivan said.

‘The new design includes a major re-shaping of the landscape and the addition of new enrichment tools such a lure which can be used to run the cats across the exhibit.'

Kaidi and Inkosana will be returned to the exhibit when it is re-opened for the September school holidays.
