Is it possible for a cat to eat moth?

I recently lost my cat (4/1/09) and have been very suspicious to her where abouts. The day before she went missing, I noticed my neighbors had covered their lawn in moth. Concerned, I search online the purpose of this. I came back with multiple searches explaining this is a method used to get rid of unwanted cats in the area. The very next day my kitty is gone. I am so uneasy about this as everyone certainly understands. There are usually 8 or 9 other cats that roam the neighborhood along with her and since her absence, I have noticed most of them to be gone as well. Is it possible they could have ingested these moth becoming sick thus crawling away to die? Or do you think the person who did this could be so irritated at the local cats that they trapped them? I just don't know what to do and maybe I am being irrational to the fact that she's gone. Any ideas about cats eating moth?
