The bedrock of innovation is improvement, improvement is something we all do automatically.
Even my dog, Pax, knows how to improve. We go through countless treat toys, toys that have a treat pouch or other means to embed or lock away a treat, something that makes getting the treat a bit harder than snapping it out of my hand. No matter how difficult they seem to be, what might take her 20 minutes the first time, only takes 10 minutes the second time and 2 minutes a week later.
Upon closer inspection I noticed she has created elaborate ways to hold down the treat with her paws, as if she has human hands, and quickly get her teeth around a small part of the treat, just enough to rip it off—or out of—the toy.
