I am lucky I got to see the fisher just 2 months ago. He was one of the most adorable animals I had ever seen. This wxhibit does not seem suited for muntjac, but i guess they are filling in a gap.
I believe it is meant to be temporary as they have 3 others in the permanent home by the elephants. It was certainly a shock for me to see this change as I was just at the zoo in the beginning of May and he was still there. My fear is that he has passed away, ever since I have been going to the zoo the fisher has always been there.
