The 4% "Other" is a category mostly of animal that died in the shelter from illness or injury. The actual total kill rate for Mayeda's shelters was actually 82% for cats. Of every 100 cats that came in, 18 left alive.
I am not aware of any large system anywhere in the United States that is so bad.
By contrast, the pie chart for Los Angeles (City) Animal Services, not considered at all near the top of the success list, shows:
The total kill rate for both euthanasia and died in the shelter is 58%, 24% less than Mayeda's kill machine.
How can County government support such poor performance? The citizens of Los Angeles City have gotten rid of a shelter manager who does twice as well as Mayeda. What on earth is wrong with the County Supervisors?
