They can take blood from horses like they do people! And the transfusion would be basically plasma with stuff added. But I am very happy to say that they have not needed to, and if Maisie continues to improve, she can come home tomorrow! They said that basically now she just needs nursing care and to be kept eating, anything at all, but eating. It is just the same as with a cat with hepatic lipidosis, give them their favourites but get them to eat. This morning she munched up a bag of carrots and ate some hay and some grains while I was there, so things are really looking up. She is off the drip now and just getting medicine by mouth. She welcomed me with a big whinny and a head butt, and stood happily while I brushed her. She still has loads of mud clinging to her from where she was rolling in it, it is a question of cleaning a little at a time. I must keep her inside when she comes home, so I have prepared a box for her in the old cow barn, where she will be warm and dry and she will be able to see Tartine in the field. Tartine was funny this morning as I was cleaning the field - she cantered rings around me, then pretended to charge me, swerving at the last moment each time. She misses having someone to play with.
