Aw, so sorry, rest in peace, pretty little Cleo. I wouldn't have put her through chemo or surgery either- the other issues make sense, in light of the new findings, & I'd have made the same choices not to let her suffer etc. If you find out more from the necropsy, I hope you'll share that here too. She looks very robust in those photos, but you can tell when an animal feels poorly.

Thank you Bogertophis. I will let everyone know what the results show.
I appreciate your empathy, kind words, and validation. I know I did the right thing, but this one stings.
