I am getting ready to move in with my mother who has two cats aged 4 and 5. I have a single cat age 3. My cat is aggressive with strangers and has never lived in a multicat home. I'm worried about her transition. I have taken her to visit at my mom's, but she has always stayed in a separate room, away from the other cats. I'm worried about her transition. I know there are articles online about introducing cats, but is there any additional advice? Should I consider using calming agents on her to help ease the transition?
