If the kitten is in control of the local animal shelter the shelter sets the rules. We have that problem here in Los Angeles. The shelters don't keep animals longer than 72 hours and then put them down. They will not turn a cat or dog over to a rescue group either so it's up to rescue groups to find a home for the animal while being under the gun on time. It is disgusting and sad but it's the way it is until each city with this kind of animal services finds a mayor without a heart of stone.
