This brings back memories. My grandparents used to take me to Gatwick Zoo during the 80s. I recall that the young Ring-tails could squeeze out between the bars of their cage. I would insist on touching them which caused my grandmother to worry and try everything to stop me (there was a sign that said something along the lines of "Danger, these animals bite")! Needless to say, I never came to any harm.
I remember Pygmy Kingfishers just inside the entrance.
