So getting your dog and cat neutered probably won't cure society of animal hoarding, but you can be sure that if there are fewer pets procreating, then there are certainly fewer pets out there to hoard.
But a month is necessary, considering that the pet overpopulation problem isn't easing up at all. Nationally, we've seen a 14 percent spike in the number of sweet dogs and cats killed at shelters because they cannot find homes.
In San Francisco, euthanasia has dropped by as much as 4 percent for dogs, according to the SPCA. That's in part because of the shelter's aggressive messaging on spaying and neutering. Still, 129 dogs and cats were euthanized at the shelter in 2009.
"There is always an overpopulation problem," said Jennifer Lu, spokeswoman with the SPCA. "We are trying to lower the number of pets that enter our shelters."
