Thanks for all your kind words and thoughts.
It's just so horrible seeing him so poorly, today he didn't wake up until 2:30pm then had some food and a wee and is back in his bed asleep

We're back at the vets tomorrow evening for fresh bloods to be sent to the lab.
I have noticed that his skin on his belly is looking yellow so I'm going to ask about that. I've been checking his gums constantly like the vet said to and they still look pink but are a little pale. His red blood cell count was down at 22 so I'm hoping its come up tomorrow.
