I am facing a horrible moral dilemma. I'm moving to Costa Rica in early July.

3. Unless you could possibly enlist a vet tech or similar to care for the cat in its last days--providing the needed $$$

to do so, I don't know what else you could do. You are right that they would not allow an FIV-positive cat to come in. It seems that would be your only alternative unless you delayed relocating for a year or so...

The cat is fortunate to have found you and to receive the care that you have provided. But, I honestly think you would have to accommodate any short-term "adopter" with the considerable funds needed to do so to be successful. The shelters are full of adult dogs and cats needing homes so the challenge would be major unless you can reach out to the right experienced person. I'm sure I'm not saying anything you don't already know, but I wish you good luck with whatever decision you make.
