The slight progress sounds encouraging. But, IMO, Meghan picking up the cat for TLC ain't a good idea just yet. You posted earlier that he has attacked her.
And, sorry to seem... I can't think of the proper word... but, rewarding a cat with affection for bad behaviour COULD encourage that behaviour. Just something to think about.
Thanks for the update and thanks to all for the posts. I am finding this quite educational. A similar situation occured with me years ago.
