I had a similar situation when I adopted Callie. She had a grown cat with her that was her kitten. At the time I felt I could only take in one cat so I left her son/daughter behind. There was a woman waiting to adopt that cat so I know it got a home but after the fact I regretted I hadn't adopted them both. I'm sure these other cats we didn't keep got good homes and we can think they probably made some one else happy to have them.
