JazMum: I am so so sorry to hear about Chloe. This is really tough. Is there anyway that you could have the vet come to your place for the final moment? we did this with Cassius; we put on some soft calming music in the background and we cuddled him in the comfort of our bed with his toys around him. it was really beautiful (considering the circumstances), and then it gives you and the family time to say goodbye in your own way and time...just a thought.
to you, your family and gorgeous Chloe.
