Thanks to all for the responses. The vet did tell my wife they could do another test. It could have been a false positive. I also read like isaland said, they canbe carriers of this but never actually have the full blown disease. We are at least hoping for that.
The animal shelter did confirm they don't test for FL because they just don't have the funds to do it. That will be a big consideration for the next cat we have and if we adopt after getting another one. But we will give her a good home for no matter how long she lives. That much we do know.
