Why Are Onions Bad for Guinea Pigs?

But then how come onions are bad for guinea pigs. They are leafy green vegetables just like other veggies. Then what is it that makes onions toxic to guinea pigs? Let’s discover.

Why Onions are Bad for Guinea Pigs?
· Disulfide and thiosulphate compounds
· Sugar and Calcium Overload
· Intense aroma and strong taste
· Too acidic

Disulfide and Thiosulphate

Onions contain disulfide and thiosulphate compounds, which are toxic to pets including guinea pigs. Guinea pigs are not able to properly digest these compounds. Their build-up leads to the clumping of hemoglobin, which in turn rupture the red blood cells. The damage to red blood cells leads to life-threatening anemia in guinea pigs. Along with anemia, disulfides also damage the respiratory tract of guinea pigs, causing serious respiratory issues.

Sugar and Calcium Overload

Onions are overloaded with calcium and sugar. Given that guinea pigs can neither deal with foods high in sugar nor foods high in calcium, onions are a big no-no for guinea pigs. Excess sugar cause digestive issues in guinea pigs. We know onions do not taste sweet but they have just way more sugar than a guinea pig can handle.

Similarly, the excessive intake of calcium causes urinary difficulties in guinea pigs. Guinea pigs can only safely eat foods that are low in calcium, so eating foods like onions that are high in calcium would cause urinary problems in guinea pigs like making bladder stones. These urinary difficulties are not really life-threatening but they can be extremely painful for our little cavies.

Aroma Too Intense and Taste Strong

Onions belong to the family Allium and are bulb vegetables. All bulb vegetables, like onions, have a too intense aroma and strong taste, which our tiny guinea pigs just cannot handle. Even large pets like cats and dogs find the smell of onions just too intense. The intense aroma of onions will result in discharge from the eyes and nose of our guinea pigs. More so, eating onion would result in excessive salivation.

Too Acidic

Raw onions are too acidic for the sensitive guinea pig internals. Onions contain sulfuric acid, which even makes us humans cry. If your guinea pig consumes onions, it will not only hurt her internals but would also result in a continuous discharge from the eyes and nose.

How Much Onion Can Kill a Guinea Pig?

Onions are toxic for guinea pigs so even eating a tiny quantity of onion would get our piglets in trouble. Eating as much as 2.5g per pound could be life-threatening for our guinea pigs. Given that most of our guinea pigs weigh around 1.5 to 2.5 pounds, eating 7.5 grams of onions could slim their chances of survival.

That said, the more onion your guinea pig eats, the greater the risk of onion toxicity and severe the illness.
