Oh thanks you guys!!!!
I went straight to the pharmacy and got some allergy tablets to take and ordered some Petal Cleanse as there's no way she's going back! I already have a steroid spray for my nose for dust/pollen/dander allergies!
I've just been home to check on her and she's fine - there were 3 massive poos in there as I think she's been holding them in! She's eating well and just wants to be cuddled and picked up
Layla is behaving normally enough - she keeps watching the door and sniffing lots, but she slept fine and is fine in herself.
I did let them see each other today through a crack in the door which Luna was attempting to squeeze through. Layla growled a very small growl and hissed, but maintained a neuteral stance (sitting down with her back slightly facing Luna) and didn't go 'big' so i'm taking this as a good sign????
There are no hives this morning, but I have made sure that i've had long sleeves on! Her claws are terrible and will really need cutting, but she's not been using them for so long that it's no wonder!
I tried to get photos but all I got were noses, bottoms and backs of heads as she wriggles and loves the camera too much!
Hope this is all normal!!!!
