this is what most of the big cat enclosures ive seen look like. poses trouble for taking photos however my camera can focus beyond. the snow leopard photos i uploaded were both taken through a fence like this but you can barely notice. its the same with the tiger photo i will be uploading shortly.
@Mzungu: It depends on what zoo you visit, as there are many large American zoos where big cats can be viewed across a moat with zero obstructions or even from behind glass. Anything is better than thick chainlink fencing.
