Why do they say Griddlebones was an agent for Macavity?

I might mention Mongojerrie. I might mention Griddlebone. There nothing more than agents for The napolien of crime.???????????????????????????

I'm not sure, a lot of people have different theories about Griddlebone being associated with Macavity. Some people think they may not even be talking about the same cat as the one in 'Growltiger's Last Stand.'
