Luckystar, I'm sorry for your loss. There was a lady on Etsy who offered pet readings which is her forte at very affordable prices. I haven't tried her for pet situations like this to be honest but I found her to be one of the 6-7 psychics who were accurate in my situation and even helped me find a lost item. Will send you her details via PM when she is back online with listings as it appears she has temporarily shut down her shop/overbooked.
Anyway, I'm getting from my tools that somebody else took her temporarily around the area and is feeding her and she is fine, however, I don't get any more info at this time. PM me if you wish with a photo of your cat and perhaps I'll get more clues to help you find her.
