My friend just got an 8 week old kitten this past weekend. She has gotten supplies for him. She got him food, toys, and a litter box. She is going to get him a bed and scratching post later. The kitten has had it's shots and checks out fine. However, she tells me that the kitten won't stop crying. It doesn't matter what time of the day or night. I figured it was just because the kitten was in a new home and new environment. Is this normal? If so, how long does it usually continue? If it is not normal, what could be the problem? Thanks.
