The other day my daughter brought home two rats. Yes, rats, not dogs. She outlined their feeding schedule, their daily routines and arranged a rat's playscape in our (mostly) unused shower.
Rats, she informed us, are a lot like dogs. They need to eat, drink, sleep, play and potty. They're motivated by positive reinforcement, e.g. treats, toys and soft touches.
Huh, I thought. Dogs are like rats and kids - so does that mean that kids are like rats? The jury is still out on that one but there are surprising similarities.
