I have an 11-year-old Siamese cat, neutered male. He has always been a talker and in years past he would occasionally sit in an empty room in the middle of the night and yell until someone appeared, but it was never a constant thing.
A year and a half ago we moved to Tokyo with our two cats and for a variety of reasons he can no longer be an indoor/outdoor cat. I take him on a walk at least once a day, he generally wants to be out for around 20 minutes before he leads us back inside.
In January, our other cat passed away. A few months after that he started being more vocal. I'm not sure if those two facts are related or not, they weren't very friendly with each other. It's been probably six months and this cat has fluctuated between "bi-hourly yowling" and "constant yowling."
Last month I brought him to the vet to address an ear infection (the only time he's been quiet was when he wasn't feeling well) and we had a senior blood panel done. Everything came back normal.
He has dry food and water always available, a spoonful of canned food once or twice a day, and 2 clean litter boxes. He has little to no interest in playing in the evening before bedtime, and in the last two days with the exception of an hour here or there, the yowling and screaming has been constant. All day and all night.
We've tried squirting with a water bottle, a calming pheromone collar, a Feliway diffuser, shutting him in our room, shutting him in a room away from us, and ignoring him, but we live so close to our neighbors (approximately 3 feet between buildings) that we can't experiment with ignoring him for hours because it's very possible he's waking them up at night.
He's quiet when he's getting undivided attention, but when he tires of that he walks into the next room and starts yelling. We don't know what else we can try.
When our other cat passed away we decided we didn't want to get another one. We anticipate moving all over the world every 3-5 years for the foreseeable future, and that's very stressful for a cat. We're thinking about fostering another cat while we're still in Tokyo, but I don't know if it would help or not.
