Question 1 if a kitten comes in sick do they kill it or treat it and put it up for adoption Question number 2 do they kill the kittens in there little deadline if no one adopts

Although they are a kill shelter, they only euthanize animals they can't medically save or those that are so aggressive, they're unadoptable. I would contact all cat rescues first before taking to a shelter.

Theyre a no kill shelter so they will treat the kittens and then put them ip for adoption

I really don't know. I would call and ask before taking kitten. There's an animal friendly place in Hillside NJ. I think on Hillside Ave.
