Mines not insulated so your one is ideal. I love dog houses they are so good for the larger tortoise and you can adapt it. think this one could house a great dane and is used purely as a second home by one big Tortoise. Congratulations on your new home and south facing ! its scorchio at the moment so I have also invested in a 'bar' umbrella for the little creeps. don't forget to post photos would love to see any set ups!
Mice galore ! I did rescue these as felt soooo sorry for them. They were wild. Wild they were livid. I even fed them via a syringe...they grew...big...and bigger...bye bye mousey into the fields....CB
