Since 2am Storm has been following me around everywhere, and meowing constinly, like when she's in heat and shes also purring like crazy. If I sit somewhere she paces, still meowing, then comes to me rubs her head on my leg/arm/head.ect and goes off again to pace or lay down, still meowing. Its now 1pm and shes still doing it. Its also her 66th or 67th day of her pregnancy. Is this normal for her getting ready to give birth?
