Someone Took My Beloved Cat

I discovered my beautiful solid white cat, Gorbi, was missing Friday morning 10/31/03
It was very puzzling because we have a fenced in yard with a "cat fence in system" so they cant get out. We have a screened in porch with a pet door so they can access the yard but not go any further. I thought I had taken all precautions to keep my cats safe.I searched over the yard then all around the fence. There was no way for him to get out, and my other cats were there. Then it started to sink in. It is halloween. I had heard of people doing bad things to cats this time of year. I have always kept them inside but I have a 15 month old who wants to pull their hair so have been keeping them out to protect them. I had a lock on the gate, but when the yard was mowed the week before it was not locked back. Now I am so grief stricken, I searched on the internet reguarding white cats and rituals and discovered solid white cats are as at risk as solid black ones this time of year because they symbolize purity. I am so grief stricken but cant grieve during the day for taking care of my son. Once he is asleep I just cry.
I cant help but imagine the horrible deeds they did to my cat. I think about his fear. He was such a loving cat, he played fetch with a small ball. I adopted him when he was just a kitten 5 years ago. I also have his mother. She seems to be looking for him and that just really breaks my heart. I am also scared now in my home. The thoughts of someone like that outside my door is so creepy. My husband is a fireman and not always available. I feel like everyone in my neighborhood should be alerted to what has happened but dont know where to start. I cant even talk about it to anyone without the fear of breaking down an crying right now.
