Do you think tortoises have episodic memories? I am trying to find out with an experiment. I place their favorite food in one of three places, this place changes on a rotating basis. Day one it is in place one day two place two etc. up to three then it repeats. So far they have not caught on to the pattern. I still put their regular food in the same place everyday just move the treat. Both my tortoises now look for the treat every morning, but they do not walk straight to where it is. They do a lap and look for it. Do you ever think they will catch on to the pattern? I have been doing this for 2 weeks now. I did notice that they always follow the same path when looking for their treat.
