Answer
There is not much I can do online but make a suggestion that they xray her skull and see if she has a foreign body in there wedged between the jaw muscle and bone. We have seen stranger things so I wouldn't be surprised. She could have had something pierce the area when she got the 'minor abrasion.'

Cats do get tetanus but you said a partial locked jaw which makes me believe there is something in there. If this hasn't been investigated it needs to be.

Otherwise you could post in the e-vet forum to Dr.Peter Knapp and ask him- he answers straight away. It is a Yahoo group. Just do a search for it.

I hope you find the answer soon!!
Please let me know what happens.
