Are there going to be animals in heaven?

Les teaches that when animal lovers ask whether there will be animals in heaven, the answer is yes. He points to the coming condition where the wolf will dwell with the lamb, the leopard will lie down with the kid, and the calf, the young lion, and the fowl are together, with a little child leading them. The cow and the bear will feed, their young will lie down together, and the lion will eat straw like the ox. This will be as it was before sin entered: neither hurting nor destroying, and the earth full of the knowledge of the Lord. Les also says the little child leading them comes from believing parents.
