We have two female 6-month-old kittens and I recently got my BFP, 4/5 weeks now. I noticed one of our cats is behaving normally, and the other is very different. She is suddenly very close to me, lying next to me, following me around - but also uncharacteristically aggressive - scratching my hands and shirt, biting, kicking with her feet. She never really did this before and I think she must be reacting to a different scent or pheromone. If anyone has any experience or advice I would love to hear it - she scratched my shirt so much this morning she got a claw stuck in the fabric.
