Javanese kittens & cats in Cookeville, Tennessee

Oscar is around 8 years old, we have had him since he was 12 weeks old. We got him from a Siamese rescue, that had an event in a Petsmart store in North Carolina. He is not in anyway aggressive, he has never bitten/attacked anyone, not even a scratch to my knowledge. He is however an extremely nervous and skittish cat. We have a large family where there is always something going on. We’ve moved twice since getting him and around 2 years ago, we moved to a new house and my elderly mom moved in to live with us. He has really become her cat and stays mostly in her room and away from everyone else, except when it’s time for his food. But he has started to pee outside of his litter box periodically now, something he randomly seems to do when there are periods of change in the home. We really feel that he just needs a new home that is much more calm and quieter than ours, with less people. Ideally an older person/couple on their own, or perhaps somebody with no young kids in the house.
