Good, I’m glad because your first post sounded like you were advocating treatment by a vet. And I was quite curious how far you would hold that stance if you had to pay taxes to cover vet treatments for stray animals.
I do agree dispatch on the spot is appropriate and shooting them for sport is not.
Treatment by a vet is an appropriate alternative; I regret that you fail to conceive that there are groups and charities unwilling to donate toward such a cause.
Remember: there are people who will one day make your same argument about the financial considerations of treating a sick “undesirable” child, senior citizens or adult before advocating sending them out to the firing range.
