Donna, I just now saw this thread. I'm so sorry that Casey is feeling so poorly. I sure hope that the nose swab and x-rays tell you something about his condition. I know how it feels to have a sick animal and not know what is wrong with them. I'm going through a similar situation with Pepper. Pepper isn't sick like Casey though. He has to go to the Vet on Wed. am for a nose swab and blood work. Prayers are on the way for sweet Casey. All fingers and paws are crossed here too. Please keep us updated.
