Thank you, Randi and Tracey.

Well, the results are back now, but... Her cystatin c is slightly decreased, but the other kidney values are fine. This is definitely good news! So far, everything I did to support her kidneys seemed to have worked!

But as expected, her blood count was as weird as usual: Leucos way too low (a little higher than they were in 2010 when they last were tested), but still very low. It used to be the same with Luna's when she was tested in 2006, 2007 and 2009. It's very likely that there's an underlying viral activity in both cats, either FIP or FIV which hasn't broken out yet. I don't think it's Feline Leukemia as both of them were tested negative in the past, and they were not exposed to any other cats ever since. However, I just made the tough decision to have Lily's blood sample (which is still at the lab's) tested for FIP, FIV, and Feline Leukemia - and now I'm nervous! I know, for the time being, it won't change a thing because they don't show any signs of illness, and I can't do anything about it, anyway. Maybe it was a wrong decision to order the tests, but on the other hand, it might help to know what we're dealing with... I'm nervous!
