Vegetable oil is used to fry food in various different culinary dishes and is popularly used around the world.
The term “vegetable oil” can be narrowly defined as referring only to plant oils that are liquid at room temperature, or broadly defined without regard to a substance’s state of matter at a given temperature.
So can guinea pigs eat vegetable oil at all?

Unfortunately, they can’t at all. It is incredibly bad for them and so is a food that needs to be kept away from them.
It will give them stomach pains if they drink it because they just can’t cope with it.
