Oh Caramel, if you were closer to Minnesota I'd want to take you home with me. Yes, please trap her, get her spayed and vaccinated, and then you can decide whether she can be added to your family, maybe be adopted by someone else, or just be released back into your own backyard. Check with animal rescue associations in your area and I'd bet you'll be able to borrow a trap and also get a very low price for her procedure.

At least, she will be vet checked and won't be adding more kittens to the homeless population of cats. She looks like a VERY sweet little girl and I'm sure there is somebody out there who would adore her.

Best of luck and love from Minnesota!
