I dont know how I missed this and so pleased you got Sky to vets in time. Getting her eating is now important
This is what happened to napoleon, he had only one working kidney and stones from the other broke up and a pieces got into his bladder.
It was made from the stuff that cannot desolve and nearly lost him during the op but he never started eating again
Birmans are so sensitive and with hindsight I so wish I had brought him home after the op but was scared that he may break the stitches internally as he probably would not have survived another op.
Please give Sky a gentle stroke from me if she will let you.
