There will be 5 cats in total.
3 are newborns, so you don't need to worry about them at all. The momma has that covered.
Keep the male cat in his kennel. we don't have him fixed yet, and we dont want the female getting pregnant again. we will be gone for about 2 weeks. It shouldn't be hard at all. all you really need to do is let the male cat out every now and then to let him use the bathroom. we have absorbent pads just incase, and well provide the food, litter, and litter box. we just cant take them with us
