Hello! I took in a stray cat who was found starving near a mall over 2 weeks ago. She checks out as healthy, no one has claimed her (age unknown, unsure if she ever had a home) and is incredibly sweet and docile. I have her in a spare room and whenever I go in, she purrs and is just so loving. I have 2 other females already who are around 3 years old. I've tried to see how they would get along by first feeding them on opposite sides of a clear barrier, and then letting the new cat out in the house while closely supervised. Unfortunately, the stray is aggressive to the point of stalking and attempting to attack my cats. I know I may be rushing things - 2+ weeks isn't that long a period of time - but I'm worried that she will hurt my cats and I'm worried that she'll never integrate. I would greatly appreciate any advice anyone has to help me!
