I think I've read somewhere that they are... but don't quote me on thatI actually think the main Paradise enclosure is good - the height, climbing opportunities and amount of foliage all being plus points. One thing that lets it down terribly is when the male and female have to be split (i.e. when the cub was born), the male is relegated to a very small seperate area. I don't know if they rotated the male / females between the two areas but even if they did I feel the smaller area is inadequate.
