Well, give it time.... we now have a new girl for Adrienne its not her sister (Erin) but she loves her the same now... We waited a well over a year before Izzy (Izabell) and thought we should just give it a try... knowing that Adrienne was feeling lost. Adrienne is now almost 3 and Izzy is 8 motnhs. You can get another little one, just have to be careful thats all.. I hate to say it but I will never get a baby kitten from a shelter again because of my expierence and they are the cause along with catteries with too many little ones and not enough litter boxes and such they all use it, so when one gets it they all carry it even if they never show signs of being sick. Babies and older cats are common with losing the battle on this.
They do have tests for FIP because Adrienne was checked and yes she is a carrier but she "outgrew" it like on most of the sites you will see this termed used. Most tests will never be perfect proof either.. as they are still trying to understand the virus. We have our local vet, emergency 24 vet, and Tufts Veterinary Medical School. Tufts did the autopsy(erin) and all of Adriennes bloodwork and random tests.
Be strong Calia!
