A dog attacks a cat. Is that news? Dogs and cats, unless brought up together, are rarely on good terms. Dogs chase cats, it's what they do. One of the Old Days sayings was 'fight like cat and dog', another long forgotten phrase.
So a dog attacks a cat.
It's not a good thing, never was.
But... is it really a police matter?
UPDATE: The original link gave no more than 'dog bites cat' but JuliaM has found more detail, which makes it a police matter for sure.
