Give her time. It's a nice day today so maybe she is running a bit later. Keep it up until it's dark. Does she ever come in the morning? You could try again then.I can't believe it, first time in 2 weeks she has not shown up! Almost like she knows. Had trouble setting trap after I had it tied open for a week. I doubt she will show tonight, I will take trap down when sun sets. Ugh
I see you live in Ohio. I am in the Columbus area. Here we have a low cost spay/neuter clinic that accepts ferals in a trap without an appointment. It really helps to take the pressure off. You might call around and see if there are any such clinics in your area. Many of the low cost clinics won't turn you away.
