Anesthesia is excreted out of the body via the kidneys. That might be a reason why Ash is not feeling up to snuff just yet. Can you please post on what you found out about the
" negatives " about sub q's. The only thing I can think of is giving too much fluids and resulting in congestive failure. BUT the vet is very specific when letting one know how much fluid to give. When our kidney cats have dentals, Dr. Deb wants them to have fluids several days before and after the dental procedure is done.

None of us want our cats to be sick/uncomfortable, we have the power to help them to have the very best quality of life that is possible. But, we also must realize that, as I told
my very first kidney cat, MissBooBoo kitty, I cannot cure you, you are not going to get better, and will not live forever. BUT, I promise you no pain, no suffering, and the BEST quality of life...Boo proceeded to live another three years!!! HANG IN THERE...
