Hellcat

A Hellcat or a Hell-kitten is a type of cat that players can only obtain after completing Freeing Evil Dave in Recipe for Disaster.



Turning your cat into a hellcat
Once you have completed Freeing Evil Dave in Recipe for Disaster, head to the basement in the house of Evil Dave's mother, Doris. Tell your kitten or cat to "Chase Vermin". After it has killed a sufficient amount of hellrats (about 7 for cats and 10 for kittens), your cat or kitten will become a Hellkitten or Hellcat. Clockwork cats cannot be turned into hell cats. It is possible to make an overgrown cat into a hellcat but it must first be made into a wily cat, after which it can become either a wily or lazy hellcat.

Hellkittens will still grow into Hellcats and Hellcats will still grow into Overgrown Hellcats. Hellcats can still be wily or lazy. To turn your Hellcat back into a regular cat, just feed it some milk. Alternatively, you can talk to Evil Dave's Mother with your cat out or have Wendy turn it purple. Hellkittens/Hellcats, eat pretty much any kind of fish, just like normal cats.

Note: There is a slim chance that only  one  hellrat is needed to be captured in order for the transformation to occure. (Although, I have had 3 hellcats, and each of them only caught one hellrat to become a hellcat.)

If you are leading a hellcat in Varrock and the stray dog begins to follow you, your hellcat will hiss at it and the dog will flee for a short time. It appears that Hellcats follow or worship Zaros. Thus their reaction when you accept the Shoo-away option: "Thank Zaros for that! Finally, some freedom from your ugly face!"



Wily and lazy hellcats
Wily cats, as well as lazy cats, can become Wily Hellcats and Lazy Hellcats by having the cat catch Hellrats or by having it as a Hellcat at an earlier age then training it to be a Wily or training it to become a Wily and letting it become Lazy.

Trivia

 * It has been confirmed that cats catch hell rats faster than kittens.
 * It is possible to transform your Kitten into Hell-kitten after just one successful capture of a Hell-Rat.
