I think I got lucky and she must have done it on the little carpet sample, which did not go through.
Friend says to get her black light and you can actually find it, or let the other cat sniff it out and just watch her.
All is much better now that I have tossed the carpet sample out.
I did Fabreeze and the stuff I got at the hardware. I'll get a bottle of what mewzilla said next time I find myself in town.
Thanks again.
