nnikol,it must be so very heartbreaking for you and nobody willing to help
Not to scare you,but like you say,cats are"stubborn"and can cause themselves to get sick by refusing to eat.
Did the fostermom tell you he is a scaredy-cat?
Since she has no intention of helping,she must not have cared much for this kitty:sad:who knows what went on before he came to you..
But then again,it's not unusual for cats to hide in a new home.
I was also thinking of scaring him out
like banging on the ceiling,but it could be very risky,he could go further in,right?
Or is the spot where he is as far as he can go???
