Benefits of Eating Poop (Cecotropes)

As mentioned earlier, guinea pigs’ cecotropes are a rich source of fiber, which allows easy digestion of food. Apart from this, their poop provides other health benefits.

Here are some of them:

1. Builds up the Nerve and Skin Tissues

Vitamin B complex and protein are some of the nutrients in cecal poop. When absorbed in the body of guinea pigs, they help to improve their overall health.

With time, these nutrients build up the skin tissues, nerves and allow easy bowel movement in cavies.

2. Helps a Sick Cavy to Recover Quickly

Based on the experiences of some guinea pig parents, the poop of a healthy cavy heals a sick one. Although it sounds strange, it is highly recommended.

Being smart, little creatures, your guinea pigs know the health benefits of others’ poop. So whenever they are sick, they move around the cage to eat the cecotropes of others.

Within a few days, the sick cavy will recover from sickness.

But bear in mind that some sicknesses will need the help of your vet. In the case of your guinea pigs’ health, never leave anything to chance.

3. Improves Blood Function

Another nutrient found in guinea pigs’ poop is vitamin K. It is useful for regulating calcium in the blood and also builds strong bones.

When there is a moderate amount of calcium in the blood, your cavies’ chances of having urinary problems will be small.

Moreover, your guinea pigs will hardly fall sick if their blood is healthy.
