hello! I have sibling desert tortoises, a little over 3 years old and I believe are both female. I have an outdoor enclosure for them but bring them in at night because it’s been cooler temps. I put a heating pad in each of their hide away spaces but I still worry they’ll get cold. Indoors they’ve been sharing a habitat that I made out of a bookshelf. They are outgrowing this and I need to make something bigger. Question is- should I separate them? I was told that what I thought was cuddling was actually dominating behavior. Is this agressive behavior or sibling hang out time? My video would load where it shows one, with strawberry on her mouth climb down. I think she may have been blocking her sister from eating. And figuring out how to make 2 raised (this time) enclosures has been a challenge! I wish I took wood shop in school.
