Thanks everyone, Lexie seems a lot happier now thanks to the painkillers, will get test results this afternoon, fingers and paws crossed all will be ok, yes it does appear it could be stress related as she only started getting them when the other two kitties arrived, i have put a litter box upstairs for her in our bedroom as well as downstairs as the other kitties use the downstairs one too, well i have not seen nikki use it but Ellie-Mae does quite often, if it is caused through that i am not sure how to handle it as it will be ongoing, as the kitties are here to stay, and this could become very upsetting for her and very expensive as well, just have to hope all will come right, or we can de=stress her with the help of medication if need be.
