We have had the “Humane” Society of the United State’s number for many years.
Two shelters get our monthly donations, a no-kill shelter and the Humane Society of our county (unaffiliated with HSUS).
They’re local, and we get nice thank you notes from time to time along with their monthly newsletters.
When my Rocket died, they published his passing in their “In Memoriam” column on the front page.
