Just spotted the 2nd message you posted, quoted below:
"have been looking into tortoise tables, found some nice ones.
Reading up they have to be a certain size and in good gealth to hibernate, does that mean they don;t have to if they're kept warm?"
First of all, don't buy a tortoise table. I have yet to see anywhere that sells anything that would be suitable for more than the first 12-18 months, assuming you got a brand new hatchling - they're all way too small. If you provide a link I can check out what you've found, specifically, but I'd be amazed if it is big enough. They're so simple and cheap to construct, too, that buying one is a waste of money. I think there was a link to some instructions in the YahooAnswers post that I linked to in my previous message.
The "a certain size/age to hibernate" thing is a total myth. Hatchlings that hatch mid summer can and should safely be hibernated at a few months old (assuming they're a hibernating species, of course) but you really do have to know what you're doing.
They need to be the right weight for their size (no matter how small they are - it is the "in proportion" bit that's important.)
The smaller the tortoise, the more critical it is that hibernation temperatures are perfect, as any weight loss will be far more detrimental to an already tiny tortoise. I use a fridge to keep the temps at 5degC, plus/minus a degree!
Also it is VITAL that they're healthy and totally parasite-free (unlikely if you buy from a store/dealer).
They should be hibernated with empty stomachs but full bladders, after an appropriate length "wind down" period for their size (where temps are gradually reduced and the tortoise is given a period of fasting, with regular warm soaks to maintain hydration.)
I know it sounds complicated but they really are amazing pets and well worth the effort!
