Spoke to the vet at 4pm. He said that they have had Millie walking in the yard and she's a little more alert, her temperature is still high but has come down a little, she has received 1/2 of the medicine she needs. They are keeping her in over night, so I have to phone at 9am to see if she is any better, he said they may keep her in until tomorrow evening depending on how much she improves. Thankyou again for all your kind words.
I will post an update tomorrow when I know more.
