I have a 15 year old cat in my care that is not thriving. She belongs to a guy who is serving in the National Guard.

I've had her for about a year. I took her to her vet a year ago to get her UTD on shots, etc. The vet told me she has been losing about a pound every year and I was sure I could change that. My cats all are pretty plump

Well, I put her on wet food and she gained 3/4 of a pound. But at her annual checkup,she has lost that and another half pound. This week she has stopped eating almost totally. I can't get her to eat more than a half of a can of cat food in a day. She doesn't drink much either. Occasionally she will throw up part of her meal or just liquid. She's literally skin & bones. She's down to 6 pounds. The vet says her blood work is fine and nothing seems to be wrong.

Could she be ready to leave this world? I don't know if I should see another vet or just leave her alone. I can't reach her owner to ask him. I certainly don't want her to suffer. She's a sweet old gal.

I'm in a quandary. Any suggestions?
