It reminded me of my very good friend and pet,
Tiger. (That's my mom in the picture). He lived as an indoor/outdoor cat for the last twelve years and when I went to college, he stayed with my parents because he was a "country" cat who loved his outdoor time. He disappeared in early November 2007, though he'd often go on walk-a-bouts for several weeks. Two weeks later, my husband's cat (who was also living at my parent's house) was eviscerated on their porch by their neighbor's pack of dogs. They found Tiger around Thanksgiving in much the same condition, but we estimate he'd been dead about a week.
It didn't really sink in that he was gone until I took my kids to visit my parents and he didn't come to sit in my lap and drool all over me. I informed both my parents that the day I get the call that my other cat living there has been killed the same way, I'm taking one of my dad's gun and killing every dog they have. My mom said I wouldn't have to bother, she'd do it first... And we're both avid animal lovers...
