As promised, here is a lizard update. I don't write too much about them since they don't do many exciting things. They don't really enjoy intereacting with humans, so mostly they hang out in their tanks.
Andreas, however, has been a bit more visible lately. I didn't keep track, but I think I went more than a week without seeing him in October. Several times during the month, he would be out when I got home from work, but immediately retreat to his cave when he saw me enter the house.
We've switched their substrate to a sand mix again, after discussing it with their vet. These uromastyx are so frustrating! There is precious little good information about them that I've been able to find. There are big disagreements on substrate, diet, enclosures, etc. I want to provide them with the best life that I can in captivity, but I don't even know what that is!
We've been discussing building them a huge habitat in a spare bedroom; hopefully that will be a winter project.
