CCL, {{{hugs}}} to you and I really hope you go to the doctors and get your arm looked at.

As for Mr Magoo, where is his cage situated ?

If possible I would place his cage in a spare room and give him time to settle on his own. Don't let your cats in for a few days at least. I would *guess* that all the new smells were just too much for him to deal with. Try a very slow introduction

Why don't you ring a cat behaviourist, they should give 5 minutes free opinion over the phone. Maybe they can give more specific advice about blind cats.

I'm so sorry you are having problems
