Can Guinea Pigs Eat Broccoli?

Broccoli is readily available in many parts of the world, and you can transform it into many tasty dishes. However, the question of can guinea pigs eat broccoli remains, and you should consider it carefully before giving guinea pigs scrap broccoli.

The Short Answer: Can Guinea Pigs Eat Broccoli?

Guinea pigs can eat broccoli, though there is some debate if they should. As a cruciferous vegetable, broccoli can cause gas, and guinea pigs are unable to pass large quantities of gas safely. A buildup can cause medical problems, so broccoli should be considered carefully.

Additionally, broccoli is high in calcium and oxalates. These nutrients can cause bladder stones and other problems if eaten in sufficient quantities.

What Parts of Broccoli Can Guinea Pigs Eat?

All parts of broccoli are generally edible for guinea pigs, from florets to flowers to stems. If you decide to give your guinea pigs broccoli, that makes it easier. In terms of serving size, you want to keep it small, which means a single floret.

Broccoli stems are particularly valuable for guinea pigs since they are woody. Eating the stems helps file your guinea pig’s constantly growing teeth and maintains their dental health over time, so you don’t have to contend with teeth trimming.

What About Broccoli is Concerning for Guinea Pigs?

The big consideration with broccoli is that it causes gas. While guinea pigs fart like humans, they cannot quickly pass large quantities of gas. This situation can lead to a buildup of gas, and unfortunately, it can have immediate health consequences that require veterinary intervention.

The other issue with broccoli is some of the nutrients. If your guinea pigs end up with too much calcium or oxalates, they can become stones that the guinea pig has to pass. Because guinea pigs are so small, the chances of stones passing painlessly or without hurting something are not great.

Due to these two reasons, many guinea pig owners opt not to feed their guinea pigs broccoli at all. However, there are many other vegetables available, so the loss of one does not affect the balance of their diets.
