My cat was a beast. 20 lb Siamese cat... killed birds regularly(thanks for leaving them on my doorstep!), a squirrel once, the neighbor once complained my cat was harassing his dog, but age got to him. It reached a sad low point when he's just sitting there wearily, a bird lands three feet away, takes his food... uses his water to soften it... and eats it and he's just too tired to care. Oh well.
My dislike of dogs.... well I'm fairly certain that stems from my leg getting mauled by one as a kid.
