The pie chart shows a 79% euthanasia rate, and 8.1% "Other." "Other" refers to animals that died in the shelter while under County care from disease or poor care, or that were somehow lost. In effect, we have an 87% kill rate!
There is no other large shelter system in the United States nearly as bad.
The 86% kill applies to all cats impounded, lost strays, owner turn-ins, kittens and ferals. A feral cat is almost impossible to adopt out. The kill rate for ferals is near 100%.
