Oh Tink, I'm so sorry. All of your kindness of finding people who wanted them and some critter has to destroy that.
Do you have a dog? We have 2 and never have racoons in our back yard. They'll come in the front yard but not the back. Same with bunnies. All of our neighbors have been fighting bunnies this summer and we haven't had any problem at all with them. I'm sure this is because our dogs chase them and apparently the bunnies know it by now. Our dogs don't stay outside, just are out a lot during the day and evenings when any of us are out.
