Another thing, you could always request to have a blood test to check for antibodies, if you have always had or been aorund cats, there is a chance you may have had it already. I think its like having a cold.
But thats said, The chances are pretty slim given you have myself & other vet nurses working with cats & their poo everyday who haven't had it.

Personally It really isn't something that needs to be discussed with your GP. Maintain a healthy & hygenic partenership with your cat & you should have no need for concern.
