You know since you mentioned it, you may really want to consider keeping her as an indoor kitty. It would definately avoid this type of situation. I know that it is hard with a cat that has been in/out. If she fights it too much consider only supervised forays to the outside. This is really only a suggestion.
actualy i am going to start working on a outdoor cat run this weekend as she love to spend time basking in the sun atleast she will be safe from the toms.

Thankyou for your kind thoughts, i am sure the vet will do a fine job as she did after Yumi decided to wrestle with a possum last year. That girl is accident prone.
