My two year old rescue is a female, calico. She is an indoor/outdoor cat who is scared very easily, therefore we have not spayed her yet. Many times shes seemed to be in heat, but has never been pregnant. When she does let me feel of her, it seems like she has no nipples and is very loose around her lower stomach area. Im wondering if it is possible for a female cat to be born without reproductive organs, or if they can be damaged somehow?
