Thank you everyone. Freya is staying at the vets for fluids, syringe feeding and observation. The on call vet will be checking on her and giving her fluids every three hours during the night (she's also on a drip) and he will ring me in the night if there are any changes. If not I'm going in at half eight tomorrow morning to take my kitten in to be spayed and will go and see her then.
I was concerned that she had fallen and injured her back because of the way she was splayed out but the vet x-rayed her straight away and they were all find which is good.
I'll let you guys know how she is.
Wallace has been cheering me up though, he's adorable! Had lots of cuddles, he climbed up onto my shoulder so I put my back against the sofa where my partner was and he climbed into him and had a good ol' explore and a bite of a few buttons.
