You will be using a trap, right? That's pretty much the only safe way to do it - for kitty and for DH!
If you're borrowing one, give it a wash - get the scent of fear and other cats off of it. Has anyone been feeding it? Because having a regular feeding schedule REALLY helps - then the day before you want to trap, put out food, but like almost none, so kitty is good and hungry the next day.
Covering the trap in sticks and leaves can help. Even better is pouring potting soil over the bottom of the trap - kitty doesn't have to walk on the wires, and the trap lifts right up through it.
Then use a REALLY stinky food, like tuna, mackerel, salmon or herring can help.
Make SURE you have a plastic tarp down in the car wherever you're going to put the trap. Almost every feral we've trapped has peed, pooped or vomited out of fear on the drive to the vet.
MUCH easier to clean up if you're prepared.
Do you have any idea how old the feral kitty is?
I'm so excited for you! I really hope all goes well!
