West Los Angeles Animal Hospital may be the apotheosis of corporate veterinary care. When it became VCA’s first purchase, in 1986, it was already the biggest pet hospital west of the Mississippi River. Today it occupies a three-story building with an attached parking garage and is staffed by 60 doctors, including cardiologists, neurologists, oncologists, even a psychologist. There are underwater treadmills for overweight cats and gimpy dogs and a sterile isolation room for pets recovering from bone marrow transplants, a cancer treatment that can easily cost $16,000. “All the advancements that you hear about in veterinary medicine? None of that would be possible if it was just your neighbor working by himself like it used to be,” says VCA Chief Executive Officer Bob Antin.
