Due to the high number of responses I received from last month’s column, "Pet abandonment and overpopulation in Auburn," I thought it best to follow up with some controversial spay-and-neuter stats and some local support for the prevention of unwanted litters and animals in Auburn. Unfortunately, this does not directly address issues of why humans do these things to innocent animals. It does address overpopulation prevention and overpopulation's effect on the increased potential for abandonment, abuse, neglect, unwanted litters and the feral population. Euthanasia has not worked to limit or control pet overpopulation, diminish kill shelters or reduce homelessness. Spaying and neutering does.
