God I'm envious now, the only animal I have NEVER seen at Dudley, despite many visits! I've even had more success with the squirrels than the cat.![]()
Granted I've only been there twice, but in my experience the key is to spend the day going around the zoo, so that by one or two hours before closing time you've seen everything and can spare a little longer than usual in front of the enclosure, as he seems to be very active from about 3pm onward, going into his offshow quarters and back out again very regularly - this of course means you can easily miss him if you only spend a minute or two looking.
Downside is, he generally moves so fast and the mesh of his enclosure is so fine that it is extremely hard to get a photo of him even when he is visible!
