Have you ever seen a chihuahua chase an American Staffordshire Terrier? And then watched those same two dogs, differing in more than 60 pounds, lay down together to sleep, with an orange cat curled at their backs.
My animals are fairly hilarious. I think the cat thinks its a dog, and the AmStaff thinks he's around 10 pounds, not 65.
But they are wonderful sleeping companions when my Patrick dear is out of town.
