Title: Clean up Cats

Everyone likes clean cats. I was told that my family once had a cat - when they lived in South Africa. That is, way before I was born. I have never had a cat, that is why I am going to be putting this on *every* new site.

As an aside from the story, I cleaned up the code. Made sense to not be calling `nodes()` twice as ultimately there's no gain from it at all.

Also, the `loop()`, `w` and `d` variables were defined, and not used extensively, so I've made them have much more use.

I didn't re-minimise/compress the code 'cause y'know, I'm a dog person.
