I have a 7 year old cat and a 1 year old cat. I had fostered before I got the 1 year old and my older cat didn't seem to mind, so we have it another go and agreed to foster a young kitten with a cold. We quarantine her in a separate room from my resident cats.
A few days ago, the kitten bolted out of the room and ran down the hall and was stopped by the one year old cat, who looked spooked by this new thing in the house. Since then, he has not wanted me to touch or pick him up, and he never sleeps on my bed with me like he used to.
I love fostering, but I want my resident cat to be happy and loving like he once was. How do I get him back to his old self? Should I introduce them when the kitten is healthy again?
