Guys, serious responses please.
She went missing yesterday morning. In the evening I went up to the top floor to start searching and I can hear her meowing.
Called BOMBA and JPAM, they arrived and checked the water/ drain pipe all the way down but she's not there. And they said nothing much can be done because they don't know exactly where she is.

Today morning I can still hear her meowing. She's somewhere inside the roof.
Building maintenance doesn't have the capability to deal with such a situation.

She's a stray that I usually feed. She has gone missing once before and I found her on the roof of the 16th floor, but when she saw me she got back out.  This time I can only hear her and she can here me. But we cannot see her at all.
No, we don't know how she got onto the roof. I believe some people put here there deliberately or she would have gotten into the lifts herself and wandered around.

What should I do?




BTW this is a post regarding the heroes of this particular fiasco: Thank you!
