One of my girls was hardly moving and seemed to be blind. Took her to the vets and she said that she's got a virus that is affecting the nerves. Which is why she can't see, drink,eat , move around etc. we have been hand feeding her since Monday and Tuesday she ate loads by herself, but now she's not, and we have to open her mouth to feed her and syringe water into her mouth.. She's on metacam ( pain relief and anti inflammatory ) but I don't want to make her miserable as the vet said there's a 50/50 percent chance she will over come it. How long should I wait till enough is enough?
