We have had Alfa now for about two months. We purchased him from a private zoo where he was housed on pure sand and concrete. We spent many hours watching him at the zoo prior to purchasing him and decided he was perfect for our breeding program despite his obvious classic signs of depression. The day we took possession of Alfa, the zoo owner disclosed that the zoo vet had diagnosed him with depression several years back and that he had lost a lot of weight. Anyway, we are convinced that he was very depressed based on what we see now. He is not the same tortoise that we saw in the zoo environment, he seems so happy and at peace now in his new home. My question is do you think tortoises can get depressed when exposed to certain circumstances?
