Cincy's Mom,

Why can't he/she stay in the basement? If someone would
come to feed & clean a litter box. Maybe the kitty would learn
to trust a human who came to visit him/her there. It might be
better to earn the cat's trust in a place where the cat felt more
comfortable. It might not take as long as you think.The kitty
would have a much better chance for adoption if it could feel
more at ease with at least one person.( for starters) Good
luck with this.
