I need to trap a stay female cat. She is a little tame, but not well enough to get into a pet carrier. There are a few other strays around, but this one needs to go first. I'm hoping to get her to the vet and have her spayed. How do I go about trapping the right one, or do I just keep trapping until I get her. Also, I can't find anyone with a humane trap. Where can I find a cheap one that will work....know of any sites. Thanks.
