A quick update Emily was checked over by Sean and she's absolutely fine, apart from me discovering just before she went, she was actually a little boy
He didn't advise rehoming her with other cats
just in case she is a shedder and if she is, obviously the stress of moving her etc would bring this out if she is a carrier. Smokie obviously passed on something to the whole litter whilst she was carrying but all her bloods were clear so we still don't know what caused it. To be on the safe side, she won't be for rehoming or he I should say.
He's still a little buggar and is into everything but he is at the moment happy and healthy, and I hope he continues to remain so
