So can guinea pigs feel sad?
Guinea pigs are sensitive creatures. As prey animals they have the ability to sense emotions that maybe others can’t. If they do sense that the one that protects them is sad, they will want to know why and come to be sad as well. If they sense that their owner is scared they will be scared too. Prey animals do have the ability to protect and watch out for one another. This is even the case with their protectors.
