Oh my god, if a cat is growling or hissing at you don't try and corner it, touch it. Growling and hissing is a WARNING, they want you to back off. I get you were scared that the cat was going to jump over the fence and not come home. But, you antagonized it and it bit you and scratched you. If you are going to have an animal do some fucking research!

Also, YELLING at the animal for having a natural reaction to fear, annoyance etc...is counterproductive. I mean...fucking dear god ... do some minimal research.
