Christie Keith, social media adviser for animal welfare organizations, said in 2012 that the use of the term "overpopulation" to justify shelter killings involves the logical fallacy of a tautology. If a shelter with no adoption program was able to save more animals when a program was added and then enhanced, was the improvement in save rates due to a "Reduction in 'pet over-population'? Or improvement in shelter management practices?" When communities are able to save more than 90% of the animals admitted, Keith asks, "Did they reduce 'pet over-population,' or did they become a no-kill community by implementing modern, proven, progressive sheltering practices?"
