Sometimes I think I use too many superlatives in my reviews (Happy Traveller ;-) ), but this was such a great experience. You can cuddle lion cubs (it was too hot in the afternoon, so they were a little grumpy) and play with young lions (several months old), but also walk with adult lions. The staff took us out (9 of us) with 2 young adult lions and threw and placed chicken around so we could observe them. An absolutely enjoyable and informative time.
There are also tigers and other cats and the guides explained the differences in their behaviour brilliantly.
