"The thing is it should be decades now since anybody was surprised by animals making and using tools. Oh, it used to be trendy to say humans were the only animals who used tools to blush, but that crashed once animal researchers tried actually looking at the animals they were researching. Today we know that humans are the only animals who toss the warranty registration cards for their tools in the kitchen drawer that will never be cleaned out because it's too hard to fully open and too depressing to sort fully through.
"Meanwhile we see animal tool use all over the place and providing an important part of the economy such as it is. For example, nearly two-thirds of all Craftsman tools are sold to tree-dwelling creatures not more than eighteen inches long. Nearly the entire world supply of rotary sanders have been purchased by squirrels, which is one of the ways to distinguish them from chipmunks, who prefer belt sanders."
