Why won't my cat stop meowing?
No matter what I do my cat won't stop meowing. it's like 24/7 almost. I know she gets louder when she wants water or food or something but even when she has water and food and is getting my full attention she just doesn't stop!! Only reason I am frustrated now is because I am about to have a baby and if she keeps me up at night then I worry she will keep the baby up at night. Help please!!
it probably wants attention to play or something?

Has she been spade. When a female is in heet she will meow like crazy, and demand alot of attention.
Something may me wrong with her that you can't see. Are there other things that she does that are unlike her? For example, water consumption, urination, appetite, any vomiting or diahrrea?
