Boy can I relate to this story! We TNR the park cats and seclude them out on our patio until we can release them. The other morning after a successful trapping session he released them. I came home to their food and water dishes still setting on the patio, and the trap cover wadded up and laying there, along with the trap. Now keep in mind you're suppose to bleach all this stuff before you use again, including trap, so you don't expose anything to any other cats. We have several ferals that come in our backyard to feed and drink and now I don't know if they were exposed to this stuff. Sometimes I could just scream!
