A woman that I work with took in a 5-6 month semi-feral kitty. They have a finished basement and took kitty down there to get used to the house. Upon release from the carrier, Kitty immediately went and hid up in their suspended ceiling. She called me for help and my friend Luana and I went over to retrieve the kitty..........BUT.......kitty had gone under a raised floor they have in the downstairs bathroom. About 8x8 square. We called and coaxed , etc, but no sign of kitty. Took flashlights and looked - but could not see kitty. Reta said kitty was coming out at night to feed and drink - but only after they had gone to bed. Two weeks of this. We set a have a heart trap and expected kitty to enter within a couple of nights....so far - no luck and Reta is getting terribly worried. They are considering taking up the floor - any other suggestions? She is azn older lady and is so blaming herself for this. I don't have any other thought. It does not appear that kitty could escape from the basement -
