The cats actually cooperated and exited when doors opened? In what lifetime? They didn't decide to stay inside, take a nap, stop to wash up first? Took Lashanna for exam and shots. She howled all the way there. Quiet at clinic but shaking like a leaf. Quiet on ride home until about a mile away, when she began to meow and try to escape carrier. Cats have excellent homing instincts. Her revenge was peeing in carrier, then tracking it across the floor before deigning to wash her paws. I just washed the floor!
