Have you noticed your guinea pig shaking or vibrating and wonder what it means? Here’s the lowdown on ‘Why do guinea pigs shake?’.
If you’re holding your guinea pig and notice that his body is shaking, it probably means that he’s quite happy and content. A guinea pig that is at ease and joyful can express his emotions by vibrating his body. Along with shaking, he will often vocalize his contentment with some wheeks or purrs.
When I first got my guinea pig, I thought the shaking was out of fear, because thats what humans do when we are afraid right? The actual science behind the shaking is something I am not completely familiar with but the vets that I have talked to said that the shaking is largely out of pleasure.
