My sorority Big Sister is a veterinarian, equine surgeon specialist. We got to talking about vet practices. A fortune is to be made if one specializes in bovines (cows). But the problem with being a large animal vet is it is hard on the body and eventually the vets either retire or downsize to dogs and cats. Another friend (coffee klatsch lady) is such a down-sized vet and now she just pops into the clinic two days a week for low-cost spay-and-neuter days. Simple stuff and not very taxing or dangerous, unlike palpating a half-ton of kicking critter.
