Hi Razzle, can totally sympathise, one of my lads decided a few years ago to get a Hermanns, he saved all his birthday and chistmas money, plus paper round money for ages.
He eventually got a tortoise, a youngster, and he was so lovely!
We did everything by the book, started him in a vivarium, then gradually moved him outside, and hibernated him in an insulated box in a fridge, as recommended.
He was thriving, then suddenly died during hibernation the winter before last:-(
We'd had him for about 5 years and had definitely formed a relationship with him, I can't look at a photo of a tortoise without a lump coming to my throat!
We buried him in the garden, don't think I'd want to preserve the shell, but each to his own:-)
