Resident cat afraid of new cat, how do I make him unafraid?
Long story short, both cats have a temperament that unknown cats are welcome so I let them meet right away. The vet says the new guy is actually around one year old, the old guy is 13. (The shelter said two years old, so I expected a certain amount of adult cat calm.)
Meeting went great, first feeding did not. The new guy was super greedy and kept sticking his head in the resident's bowl. I was worried about the resident cat because there is a size disparity. Third time, resident cat hissed at new cat, new cat backed off and went back to the other dish, and I thought the matter settled.
Nope, whenever they see each other, resident cat hisses, sometimes growls, and runs away, low to the ground. If they are both close to the dividing door, he hisses.
So new cat is locked in a bedroom that is too small for territory and clearly wants out and resident cat won't eat unless someone is near him. Family life and house maintenance is disrupted because of how many non work hours are spent in the bedroom.
I just want a peaceful and integrated home.
