In a perfect world I would love to have her back. She's my first kitty of my very own and I love her very much. But I don't know how long it's going to take me to get my own place and I don't think it's fair to let someone else fall in love with her and then make them give her up.
Some years ago, a friend of mine agreed to foster a lovely gentleman cat for some friends who were going to spend a year abroad. While those friends were abroad, my friend got the urge to do something similar, and got them to agree to foster her cat (the two cats had gotten along reasonably well) upon their return so she could go teach English in S. Korea for a year. She had some trepidation that old lady cat might not stick around for her return. But upon her return from Korea, she took both cats again, as the friends once again wished to venture far afield. She was able to be there for the last months of her old girl, and kept the big guy cat for several years before he, too went to the Rainbow Bridge. And that just beautifully cleared the way for her to be able to take in a cat who had belonged to her aged aunt who was to move into a nursing home.
I can also speak for my own experience of living with my mom when she fostered a dog, a German Shepherd mix, for a woman and her daughter, as they were moving from a house with a yard to an apartment with a weight/size limit on the pets allowed. The daughter was 18, and had planned to get her own place, hoping that she would be able to take her dog back. For a couple of years, as they kept in touch, and came to visit, sometimes sneaking him to their appartment for an overnight visit, we did get to love the dog, and yet it was the kind of love that would have rejoiced in a permanent reunion with the dog's original girl. But after a while, they quit coming around, and so the dog became a permanent member of my mom's menagerie.
