Doing recipe for disaster quest and during that help Evil Dave. you will need to kill hell rats using either a plain pet cat or kitten, then after a certain amount are killed it will turn.
You have to be a member. You buy kittens from this one person. then you can raise them normally or feed them hell rat things that will make them hell cats.
a runescape hell cat is earned from a sub quest in recipie of diaster its a quest with like 10 quests in it u get it in the middle of one of them (while freeing evil dave) u dont need to have started this quest I think go to ege vil right next to the bank is a house go into the celler and there will be hell rats kill them with ur cat and soon it will be a hell cat.
This is part of the Evil Dave Recipe for Disaster Side-Quest, you go to his basement and you set your kitten/cat on the Hell Rats and after killing a few it will turn into a hell cat/kitten. P.S you cannot do this with Overgrown/lazy Cats.
The Wilderness volcano.
You do not name any of your pets, Cats would be Cat, Kitten, Wily Cat, Lazy Cat, Overgrown Cat, and all of the above after a certain quest (I don't know which one) could become Hell Cat, Hell Kitten, Wily Hell Cat, so on so forth.
You find cats in Runescape by either looking at other people's pets, or doing the quest "Gertrude's Cat" and buying one yourself.
Hell rats can be found in Evil Dave's basement for the quest "recipe for disaster".
You get a hell cat from the quest "Recipe for Disaster". You make your cat "chase vermin" when you are near hell rats and if you do these enough it will turn into a hell cat.
You can find these Hell Rats in the sewers in Varrock, You can find Varrock by exploring your map, have fun.
A brass key.
