Hopefully this will work. I was going to suggest a live trap with yummy smelly food in it, but that could just as easily trap a skunk - not a pleasant thought!
Lol! I laugh because I haven't been so lucky yet, but it's only a matter of time. I regularly trap raccoons and I got my first possum back in May. I've gone so far as to think out my plan for releasing a skunk from the trap without getting sprayed; it involves approaching the trap holding a plastic tarp up in front of my body, head and all, and laying the tarp over the trap when I get close enough. Hopefully the tarp will be the only thing that gets "skunked".
You're not technically supposed to leave the live cat traps unattended anyway; although, you can for short periods of time, depending on the conditions and where you're trapping. There are numerous reasons why you should keep an eye on any set traps, such as being around to promptly cover the trap if a cat freaks out or to prevent people and other animals from harming or causing unnecessary stress to a trapped cat, but any trapper will tell you that you also have to be on the lookout for wildlife bycatch.
Raccoons are usually quite easy to release, although I wouldn't want to trap a baby if mom was around, but no one
wants to accidentally trap a skunk!
Interestingly enough, I opened my front door last night to take the garbage out, and there was a skunk waddling around on my front porch. Needless to say, I won't be doing any night time trapping in my own yard anytime soon.
Claiken, it's very kind of you to leave some food out for the hungry kitty.
I hope he/she comes back for it!
