I'm so sorry, causecausse
Please don't beat yourself up over this. You can only decide based on the information you're given and
everyone is urging people to stay home unless
absolutely necessary. But how do you know what's necessary without seeing the vet in the first place? It's a Catch 22 and a lot of people are being caught in similar situations.
I do think, given the renal failure and sepsis, that Pipi likely wouldn't have survived the surgery. The hardest part is that they didn't let you in the clinic to be with him.
My heart aches for you.
