Were can you find hellrats on runescapes

You can find hellrats when participating in the quest "Recipe for Disaster," where you first find all the ingredients for the things the cook needs, then an evil cook ghost invades the dinner when you get told you are invited by the cook. Someone comes and stops time in that room only before the guests are all killed by the evil cook ghost. (to everyone else they have already been saved, and you defeated the ghost) You then have to participate in 8 miniquests to get the items needed from the people who know the guests and save them from death. One of the guests is "Evil Dave" who needs a stew from his mother to be saved. You must have completed "Gertrude's Cat" and the "Shadow of the Storm" quests to be able to do this quest. You then go to Evil Dave's mother's house in Edgeville where you go to Evil Dave's evil room in the basement. To make the stew, you need spices, and the hellrats down there have stolen them, so you need your cat to catch them to retrieve those spices. After your cat catches 5-7 hellrats, it will turn into a hellcat. You cannot put hellrats on rat poles, because they are "too hot" to put on them and would burn it. Be careful though, because if you feed your cat milk, it will turn back to normal and you'll need to catch more rats.
