Animal Welfare. IMO, if they are taken care of properly, provided with good quality food, shelter, are protected from internal/external parasites, and are a well-adjusted, balanced animal(balanced mentally-Watch Cesar Milan..), then I have done my job as a Vet Tech by educating owners.
Animals do have a right to be provided all of those things I listed above, but the majority aren't. I just want to make sure they are well taken care of, and that's all I ask.
