I have noticed while reading the Medium Task selection of the Varrock Achievement Diary that there is a mistake for the task get a cat training medal from Gertrude. It says that you can't use a overgrown cat, whether it be wily or lazy, or just plain overgrown. This is an error, as I have just completed that task using a wily cat. It was incredibly effective as it had about a 99% catch rate. Whether overgrown and lazy cats catch rats, I am not sure of that. Thought you might want to update that.

It makes perfect sense that a wiley cat would catch rats like crazy.

 

 

 

And also that an overgrown, lazy cat would not be able to catch any at all.

 

 

 

I bet this has been fixed by Jagex since the guide was written.

Yes it most definately needs altering
