I keep looking and every couple of days I do see him. Now I'm just waiting for money to come through because I figure even at $3 a day, I'll use the trap long enough to just BUY the darn thing!
So I'm just going to buy one and go from there. I plan on living in this building a LONG time (until I graduate at least) so if I have to trap a different spot every day for months, I'm going to.
At this point not only do I miss him terribly, but also I am not going to let myself be beaten by a stubborn cat.
