Donna, I'm so sorry that Casey is still miserable and that you didn't find out any answers from the tests. Hopefully the nasal swab will tell you something. I had to wait almost 6 days to find out the results from this test but at least it told me what was wrong. Has Casey beed tested for FIP? When Pepper was very sick last year, the doctor tested him for feline leukemia and FIP and both were negative. Prayers are continuing to go out for sweet Casey. All fingers and paws are still crossed too. {{{{HUGS}}}}
