SInce it is the summer time we're trying really hard to keep the ferret room cooled off. Thus I decided it would probably help if we put ice cubes in their water. They love it!!! Klepto actually thinks ice cubes are toys. He scoops them out and then he pushes them around with his nose. He'll even push them down the 4 ramps and out the cage. Here is the pics of him all wet from the ice. We like to call him the elusive ice otter, lol.
