Shes almost 6 years old. The sides of her stomach are not as hard, but the bottom is REALLY hard and she does not like me touching it. Shes about 14 pounds.
Shes pregnant!
the hardness on her belly is actualy her nipples swelling up with milk.
It is natural for her to not want you to touch them, it is best if you do not pick her up or rub her belly.
If this is definately not the case, then you should take her to the vet to check if something is wrong with her.
This happened to me too!
