Hi, I have a year and half old pregnant cat (cleo), who is expecting anytime. This morning at 4am she was meowing constantly, restless and looking around, she hasnt eaten or had anything to drink, ive showed her it but she just walks away. We also have two small 6 month old kitten girls sadie and sasha and she was getting hold of their necks and pulling them into her nesting area, i then took sadie away as she was crying and cleo went mad jumping up at me to try and get to sadie, anyway i put the two girls into another room and left cleo by herself and she was constantly by my bedroom door meowing and scratching at the door, this was going on for about 3 hours, so i let the girls out and cleo settled down into her nesting area. I havent seen any discharge from her yet and feels alittle hot and shes making the sound like shes in heat, ive phoned my vet and they have told me just to keep a close eye on her. Is this a sign of her going into early labour, she wasnt like this at all yesterday, she was sitting on the window ledge.
