April is Prevention of Cruelty to Animals Month. The ASPCA has a "go orange for animals" campaign to help raise awareness to this cause.
We are wearing orange. We are wearing orange for all but particularly in honour of our Zaphod. Zaphod is a survivor of animal cruelty. We don't know what happened in his past, but we know it wasn't nice. We wear orange to raise awareness to help prevent other dogs from suffering like Zaphod has.
