Joy, you have done so much for the beautiful Peggy Sue, and I'm sending love and best wishes for you all.
I love rescuing little things like lizards and tiny snakes the cats bring in from their outdoor enclosure. I even rescued a mouse once - was a great picture with 5 cats wrapped around a chair! I'll pick spiders up with a paper towel and toss them outside. A couple weeks ago, I killed a scorpion that was in a dog's dish . . . and felt bad about it. The dog had just put her nose in the dish to check it out, and I chose to save the dog from an ER visit!! Sometimes it's hard to save all, but I do share your sentiments.
Oops - I don't save fire ants either.
