This is good news. Our animals are plagued by tick fever, every worm imaginable and a host of illnesses so unless a healthy animal is actually taken care of by belonging to a responsible owner he won't stay healthy for long. The strays are out there scavenging for food and fighting with raccoons and not necessarily getting their vaccinations etc.
I agree that euthanizing healthy animals is a shame, but letting an animal struggle, get ill, starve and suffer while enjoying the "freedom" of the streets and beaches really isn't a responsible thing for us to do as a community.
Please post the cost per shot or a suggested amount of donation for folks to make that will help towards the program. A pledge system would be sustainable, say $5 per month per donor (for example) so that you can guarantee that in the future the town won't be put in the position again of having to use poison because the donation well has run dry.
