Im tortoise sitting for a friend who is on holiday for three weeks and Im increasingly concerned that the tortoise is not eating anything. Its a large tortoise (no idea what type) that has the free run of her house/patio. Im bathing the tortoise in warm water and he is drinking and he walks around the house, but he wont eat - even when I try to hand feed him. She has left a selection of cabbage/ watercress/ apple in the fridge for him. Ive tried them all, but no luck.
Ive been reading stuff on-line and I think the problem is that its so cold and he needs a basking lamp, but Im no expert. I also have no idea how to use one, or even where to get one (assuming that that is what he needs)
I think I need a lot of advice please

What's there usual set up ? If its cool were you are try using a table lamp with the bendy necks that you would on a computer bench or bedside table , how long has it been since it ate ? The diets not the best but try a bit of cucumber or green beans but avoid the fruit and cabbage as there not good for torts guts and cabbage stops calcium in There diet
Hope it picks up soon
