Not 100% sure but I'd say its not a yote. I've never seen one leave any part of a kill. We've lost plenty of cats and they just dissappear. Yote, will kill and immediately eat rodents and carry off larger prey. Though I don't know how those that have adapted to city life act.
If you're good with the bow (instinctive shooting) I'd consider setting up a night or very early morning shot.
Ya gotta be careful though, those green belt walkers bleed easily.
If you're near Seattle, I'll be in Kirkland over the 4th. I could bring my 375 H&H, its fairly quiet
