hello, ive recently acquired a 9 year old horsefield tortoise from a family member as they no longer wanted him/her. hes been living in a large vivarium all his life with wood chippings on the floor, no where to burrow or climb on and after doing some reading i have discovered that this isnt the correct way to house him. im not really sure whether i should be putting him outside or inside as hes 9 so is that classed as an adult or juviniel. also hes always had heat and tends to sleep more in the summer than in the winter as weve had him for a week now and he hardly moves only to try and dig into the plastic of the vivaruim. can anyone give me some advise on how to house him because i feel that i need some help to get his standard of living where it needs to be. thankyou.
