OMG, that's hilarious! The airplane ears are just too funny! Don't worry, they'll get used to each other and become good friends. I had 4 cats when I rescued a Border Collie. My 5 lbs. of pure terror, Puddy, didn't like the idea of Heidi, the dog, interloping into her territory. As a matter of fact, they all put up a fuss. Later, though, Puddy got a charge out of playing w/Heidi's tail and Heidi would curl her lip in the Elvis mode but never even growled at her. Eventually, Puddy slept on Heidi's back. So give it time. Chaos will soon turn into bliss. Just watch. And Callie is adorable!
