Hi Lara and Kitt:

I told him about the needle stick but both he and my cat's vet didn't think it would be likely to contract something since there are very few things humans can can get from a cat (e.g. taxoplasmosis). My old cat has always been indoors and has had her vaccinations, so that also rules out rabies.

Hopefully the muscle twitching will subside in line with my stress levels, which have admittedly been fairly high of late.
