I am so sorry this happened to your kitty and your family! I agree with everyone here, but the bottom line is that the husband told you his step-son threw a cat away. You have the right to ask him if he would allow you to at least see the poor cat in his garbage. If it is yours, you take her home and give her the proper burial your family needs. If he's a cop, he should respect that you want to see evidence or identify remains. We have the neighbors from hell by our house and I can tell you that walking on eggshells around neighbors and trying to keep the peace by never standing up for yourself and what you know is right, is not the best answer in every situation. Go and get your cat, please. Don't be intimidated by them...at least ask...I understand you don't want to "start" anything, if they don't let you see their trash for some reason, maybe you can have someone wait for the garbage man and tell him what happened and ask him to gently empty the can so you can try to get the cat out. Oh, I wish I could help you more. Best wishes to you and your family...
