We've decided to put him to sleep. The vet was lovely, she has guinea pigs herself, and told us the options.
It looks like he had a prolapse from straining and the complication would have been too much for him at his weight in surgery. I'm a wreck but I'm not going to consider options for wilbur until I'm clear headed, my knee jerk reaction is to rehome him but doubt I'll want that in the end. Ozzy was just quiet and in too much pain, I feel so guilty he dropped so much weight, it happened so quickly. But at least he won't be in pain anymore.
BIG HUGS
I am so sorry that the news was devstating. You have done absolutely the right thing nd not failed Ozzy in any way, including by giving him the most loving loving but also most heartbreaking gift there is for any owner. Sometimes we cannot make a piggy well again; that is not in our power. We can only care for them, see a vet and ensure that they do not suffer unncessarily. The rest is not in our control.
Please be aware that the feelings of guilt/failure/intense soul searching that characterise the onset of the grieving process are always much stronger after pts (euthanasia), especially when it comes as a shock decision. Give yourself time to not be OK but please be kind with yourself; there is no fault attached to Ozzy's passing. Just sheer bad luck in pulling one of the short straws in the cosmic lottery of rare complications.
As long as Wilbur is eating and drinking he will keep for a few weeks .
You can find more information on what to for bereaved companions, pts and end of life decisions (if you feel the need to go over that again) and on human grieving to make sense of your overwhelming but often conflicting and unexpected emotions via this link here:

PS: Unfortunately, the system is now broken re. guinea pigs as well. Please do not give Wilbur away (rescues are full) ad rather consider rehoming a new companion in due time.

But most importantly, take your time - you have enough enough wiggle space. You are a very loving owner; please do not choke your ability and your need to love just because you hurt. Love and grieving are the two sides of the same coin but it is in the dark and the grieving that we make deep roots as human to grow stronger and become emotionally more aware. It is not just lost time and pain. It is what you do with your experience afterwards.
