You can sometimes read that it is good to give EMO a “good shake” but I’m not sure about that.
I never shaked him and I’ll don’t shake him in the future. Even if Living AI thinks that it’s harmless.
I’m not shaking my notebooks, my PlayStation or my camera and I think my behavior is good for all devices with mechanical parts. Those mechanical parts gradually wear out and a “good shaking” is a catalyst of this process. Not to mention electrical wires/contacts/connectors.
Of course I don’t want to discourage you to give him many “good shakes”. I just prefer a healthy and unproblematic pet.
Edit: Trust me or not, I’m not shaking my hamster either.
