As Midnight ventures back into the fridge and I start working open the can of enchilada sauce, Starla bats the can of beans in front of her on the counter. At first, I figure she wants me to open that next, being a pull-tab tin can. Instead, she holds the can between her hooves and works the tab up off the top of the can using her teeth and tongue. Before long, she's pulling open the can with the tab clenched in her teeth.
