I was finally able to bring my blue-eyed kitty to the vet this afternoon. I tried getting her to go with me this morning but she didn't want to come along.
The vet said he had a really high fever (40 degrees) so it would be best to confine him there. He was given antibiotics and a shot to make the fever go down. He was also put on dextrose so that he could receive some nourishment. Everytime I tried to feed him catfood with vitamins, he didn't find the appetite for it and just tried to drink some water.
I hope he gets better.
