If the crazy cat lady can see who visited the people (showing exact names of people who visited which cat's house), but not know the exact role of each cat, it wouldn't be bad. But it might be a bit underpowered or perhaps overpowered. Either way, the Jester/Arson combo needs a town counter for it, otherwise Arson has a really hard time claiming. That's probably one of the greatest weakness of that and the SK, the SK and arson both have terrible counter claims for them - vig or jester, which are both very easy to disprove if you have a survivor claim or no confirmed vig kills.
