Would recommend the feeding tour over the awareness tour. You get real close to the big cats (close enough the tour guide has to give the spray warning speech - which was not an issue during our tour. The place has about 25 tigers but you will only encounter several during the walking tour. But there are also lions, a jaguar, a bobcat, monkeys, lemurs, horses and a llama.
The tour guide was informative and willing to answer questions. The focus was on the personalities of the big cats and the care the sanctuary provided.
It was the favorite part of the trip for the pre-teen.
