The live release rate has become the number one statistic that governmental elected staff use to evaluate the performance of their animal shelter. These folks are deaf to the obstacles that prevent a 90% live release rate, like their citizens breeding their pets like crazy.
One path to No Kill is to get your elected folks so worked up about saving all of the animals that you get them to make a declaration of No Kill. That commitment now opens all of the doors to fund a solution. Austin Texas is a good example as to declaring its intent and then being forced to build a new shelter and add new personnel to maintain their No Kill status. They even experienced the side effect of citizens from neighboring cities and counties bringing their pets to Austin. After all, if your want to feel good about abandoning your pet, take the pet to a no kill facility.
Most communities cannot afford to keep throwing money at their animal shelter to boast of being No Kill, so an alternate solution is to begin training your citizens to become responsible pet owners: to encourage pet licensing and spaying and neutering.
Pet laws should be geared to impacting the owners who allow their fertile pets from running at large. Some shelters offer programs that reduce the reclaim rate of bailing your pet out of the shelter if the owner allows the pet to be sterilized. Those shelters frequently demand that owners who continuously allow their pets to run loose without identification must microchip their pets. The purpose of these laws are to force bad pet owners into taking responsible measures for their pets.
