i have a horsfield called Marvin he is around 4 I think I inherited him a year ago, he is kept in a tortoise table he has a lamp for heat and a UV lamp. Previously before I had him he only had a heat lamp. Part of his shell started to feel hollow on top, I took him to my vet who was pretty hopeless and didn't have a clue, promised to take advice and get back to me. I realised later the problem is he had been damaging his shell by banging it in his wooden shelter as he outgrown it, he now has one of the rabbit cane ones which you bend to shape, much bigger and he has plenty of space. The problem now is his topmost scute has lifted off, another seems to be loosening too, the bone underneath seems ok there is no redness at edges just seems solid. What do I do now? He is healthy eating well and extremely active. I'll add pictures. Thank you in advance for any advice... Caroline
