Sending prayers and vibes that you catch him soon! if you live near the woods, you can use human urine to mark territory. it is the language that canines, especially coyotes and wolves, recognize and respect. it sounds gross but it is an old-timer's trick that works. with the moon waxing full. now is the time, especially if you hear howling and tipping. Coyotes move about their territory, like a circuit, so they instinctively avoid over-hunting an area.
I appreciate your worry. Your cat, however, shows good survival skills by knowing how to go up a tree, where he will be safe from the biggest threats of coyotes, dogs, owls and cars. Keep trying to get him, keep establishing your territory and keep your faith up. The calmer that you are, the more secure he will feel. I have inside-outside cars who get skittish as soon as they get outside - it is very frustrating.

If it is from your cats' housemate, it may help him feel secure. But to deter predators, use human urine - little country boys love that "chore"
