The only guilt I feel is, ironically, that I allowed myself to be persuaded to increase his dose of Marbocyl, when my 'gut' told me it was not agreeing with him ; I'm 100% certain that he died this soon because his body found it toxic for some reason ; and, yes, the recent weight gain was almost certainly due to fluid build-up, which we should have thought of (my wife Ros rescues hedgehogs), so that's another big minus for me.Sleep tight Jake.
You did everything possible to make him well, I know it's awful & expensive, but an autopsy may show the problem. Then you will have a head start on any other similar problem.
Don't feel guilty you have been amazing all the way through, & given the best of care.
Aw, what a beautiful tribute to Jake from your lovely Granddaughter x so sorry you lost him x
