How long should a cat be in labor

Labor and Delivery in Felines: Breeding Tips for Healthy Kittens from HDW Enterprises and Foothill Felines Bengals. this is the best I can do for you. I help to find unwanted kittens and cats get spayed/neutered so that this problem is prevented. So please spay and neuter your pets ,you don't know how they are treated once they leave your home and we have 100's of thousand of kittens and cats put to death each year in over crowded shelters. Also if this is a stray that you have found please consider spaying her or turning her and her kittens over to a shelter that will. Good luck :)
