Well, you seem to be confused...
The cat couldn't have visited Cash because Cash himself might have been the cat... Secondly, the newspaper clearly states that the witness didn't remember the killer...
And in general, everything you wrote seems a bit far-fetched.
I think Cash was the Jumper. He was elusive and often nervous. And the Cat was watching Cash himself, not his killer. There's also a possibility that Cash was banned.))
And this is just my IMHO.
