Thank you all, your words have made me feel a lot better.
I'm not worried about this cat sitter, because she's one of the hardcore fighters here (she was recommended to me by one of the big activists, these women are often under death threats and still continue caring for the strays) and I know she would come for free if she knew I had abandoned Prince for 2 weeks and didn't care. She (like me and the other fighters) are always on the move when we hear of a cat in need. She also has a lot of experience with cats, much more than me, and it took her 2 seconds to coo Prince to sit on her lap, when it takes ME about an hour till he agrees. So I know she'll do her work, won't slack. She also decided to feed my strays during the 2 weeks, even though I'm not paying her for it, just because she wants to be sure they're well taken care of and trusts herself better than anyone else we might find. If Prince got sick or something, I know she has the best connections to get him vet care fast and even for free or strongly subsidized, and she has a car. He's better off with her than with me in that sense. If she ever goes away, I'll probably be her cat sitter.
I also know if he was showing signs of distress she would take him home with her. The only reason she and I decided not to take him to her home is her 4 cats. He would have to be confined to 1 room for the 2 weeks, which is what we want to avoid.
But the fact that he will be alone almost all the time for 2 weeks is what makes me cringe. Unfortunately, I don't have anyone at all who would come visit him, and paying her extra to come for longer periods would cost me the price of the plane ticket that I'm trying to save.
It's the funny thing with cats. Because they are so territorial, they live life alone, even though they don't like it. I see my strays, all scattered in the neighborhood and lonely without other cats, but they suffer more if they have to share a territory. In cat hotels, cats are not confined to a small room, they have a wonderful time playing in the yard with each other.
My boss said that when I return from this trip I may have to fly to the US, California (which is the other end of the world from where I am) for a week, but I don't think it's going to happen.
