Well Kyla's first blood test results came back today - they are negative for Cushings, but the lab still think that is the problem due to her history {repeated UTIs}. The vets are taking her in for the day tomorrow, to do some further investigations on her bladder, also a Low Dose Dexamethasone Suppression Test for Cushings.

I will keep you posted - thanks to those who have kindly PM'd, I will get back to you very shortly
