Physicians used to make house calls. Today, a few veterinarians still do. Duncan MacVean, DVM, is one such vet. His patients range from cats and dogs to pigs and lizards—each of them a unique personality. Every animal and every home is different, but every owner is the same in their affection for their companions. Without warning, MacVean finds himself in odd situations: stepping into a basement full of free-flying bats or struck speechless by a pig who loves opera so much that she falls into a trance.
