I'm really upset

that my cat has been missing for about a month.
My cat is my best friend and I love her.
My cat also has gone through so much.
She has run away once and has gotten run over by a car. And now she is gone.

I don't show it but it really really upsets me. My cat is a part of my family and she loves me no matter what.

I'm really sad that she's gone.

Allison found her collar on our front porch. It makes me wonder if someone took her.
