Oh bless her.
My husband once got a similar letter from an old lady in our village.
Some blokes had set their Lurchers on her cat in the field behind her cottage...he heard a commotion as he was checking the horses, so ran over.
These idiots thought it was funny to set the dogs on her cat. The old lady was shouting and crying, but could only watch in horror.
My husband got the dogs off, but there was nothing he could do for the cat, he was dead, ripped to bits. He wrapped him up in his jumper, sat with her and called her daughter to come over, then buried the cat there and then for her.
