HI there hoping for some advice.. My foster kitty Chloe is approximately 6/7 weeks pregnant now as advised by our vet. I can feel the kits moving and her nipples have filled up with milk, she has licked the hair from them too.. Her tummy is swollen and very hard... Since we brought her home she has been inseparable with my ex rescue cat Bella.. they also together and she grooms Bella almost 24/7... Last night Chloe's behavior changed suddenly.. She acted like she was in heat calling and rolling around on the ground licking her privates and then she within a second turned on Bella chasing her around the house seemingly trying to kill her.. The whole house was up turned by the time I caught her.. I have separate d the cats into different sections of the house. Do you think that maybe she is due sooner? Will she stop trying to kill Bella.. Is this normal?
