I am not surprised, this was an everyday sight when I was living in another part of a town.
Somebody would toss kittens either in the garbage bin or near the school hoping somebody will take care of them.
Animals would usually fall victim to some illness or hunger, unless somebody took them.
I called some communities for which I knew they were collecting cat food across the town, but I would got one the same answer.
They don't take cats in.
They why do you collect food?
I am not sorry for adult cats, because they can take care of themselves, but kittens without a mother they are dead in a day.
