Ocular nerves in a cat

Question
My wife and I save cats we currently have 12 strys that we are caring for. Recently we had four of the cats to the local shelter to get a rabies shot. The technician administered the shots to the back of the neck at the base. The next day, Gray's eyes seemed to be rolling to the outside edges of his head (directly opposite in an East & West directions.
At this time Gray is fine and seems to have suffered no vision loss. My question is: Is it posssible that this condition was the result of a nerve being injured when the shot was administered. I'm not looking to place blame, rather to educate myself for future situations.

Thank you for your help,
Rescuingly yours,
Bill D.

Answer
no, the scruff of the neck is so dense that its hard to cause problems in that spot.

BUT I am concerned that the tech admistered a shot there. The AAFP (do a google search) advises that vaccines should be given in seperate spots on the body.

right rear leg for rabies
right front shoulder for the distemper
left hind leg for leukemia
and left front shoulder for all other vaccines

NOW, your cat can develope a fibrosarcoma from a rabies vaccines (depends on the brand and its rare that it does happen) the margins that have to be taken are very wide to the point that surgery may be for a loss.

please speak to your shelter that they need to get up to date on where vaccines need to be given. This way they are able to track if there is a reaction.
