Risks to Consider When Feeding Nuts to Guinea Pigs

Risks to Consider When Feeding Nuts to Guinea Pigs

Sadly, guinea pigs don’t have benefits from consuming nuts. In this section, we will talk about why can’t guinea pigs eat nuts and what are the possible risk that may happen if they eat them.


Obesity Risk

Nuts are incredibly caloric. This means there is a great risk of obesity in the long run or even gaining weight rapidly. Also, they have a high content of fats too. They can deposit in the organism, clog blood vessels, and mostly contribute to weight changes and fatigue as well.

Also, even if the amounts of carbs and proteins are great for humans and provide lots of energy and satiety for the whole day, sadly, guinea pigs can not enjoy the benefits of these nutrients from nuts.


Upset Stomach and Bad Digestion

Since the nuts are very dense in many nutrients bad for the guinea pigs, we should mention how they would affect their digestion. First, they have lots of fibers.

Normally, fibers are great for improving digestion and bowel movements, but they will surely upset the stomach and cause belly aches in large amounts. All of that will cause many problems for guinea pigs such as bad digestion, loose stool, flatulence, and constant pains until the bowel movements improve.

Also, the high amount of fats is the other great enemy of the guinea pig’s digestion. Sadly, the poor little guinea pigs can not have good bowel movements if they ingest fatty foods.

And lastly, there is sugar in nuts too. It may not be a very high amount, but together with the other harmful nutrients for the guinea pig, it will cause difficulties to its digestive health.


Urinary Complications

Nuts contain mineral calcium. This mineral is harmful to the fully grown and developed guinea pigs. While they are still young, it is useful for their bones. But, later on, it’s just piling up in their urinary tract. The problems that arise from this are bladder or kidney stones, frequent urinary infections, pain during urination, or even blood in the urine. If this is not treated on time, it can lead to renal failure, which is fatal!


Guinea Pigs and Nut Allergies

Unfortunately, guinea pigs can have allergic reactions to certain foods, and nuts are one of them. There are different symptoms of nuts allergies in guinea pigs. Most common include itching, swelling of the lips, difficulties in breathing, sneezing, vomiting, diarrhea, and so on.

It is important to visit the guinea pig’s vet if you notice these symptoms before some severe allergic reactions occur.


Choking Hazard

Even though guinea pigs have strong teeth, nuts may present serious choking hazards to them due to the shape and hard texture of the nuts. Also, nuts may get stuck between their teeth which is also dangerous for guinea pigs. So, it’s better to simply avoid feeding nuts to your guinea pigs.
