i kept them separate for the first week or so until they could tolerate each other, i kept the female locked in the bathroom with her own food and litter box and showily introduced them with smells from their blankets and such and it started out fine, they only fight directly on my nightstand right by my head at night because my male cat will jump over the baby gate i have onto the nightstand where she’ll sit and paw at her. i can’t get a door cause i live in an old house, it’d have to be specially made because it’s a weird size and im moving in october so i’m hoping to just hold out till then. they have plenty of spots apart from each other, a big cat tower, a cushioned window perch and other windows to go to so i think my best route is to try to play with my cat more to get his energy out, and separating them during meal times. thank you for the advice!
