Are there any risks attached to feeding my Guinea pig chocolates? If yes, what are they?

Very fast weight gain

As we already know these treats are loaded with a lot of sugars, carbs and a lot of calories. Not to mention a lot of fat too.

That means much like humans, these treats make us and the piglet gain a lot of weight. Which is very unhealthy because it will lead to cardiovascular problems and liver failure. Ultimately death too.

Digestive tract ruckus

Like we mentioned above, there is theobromine and sugar, which is the lethal combo. Not only will it upset the digestive process, but it will cause pain to your piglet too.

Cardiovascular problems

The theobromine exhibits similar characteristics such as coffee, which is a known toxic substance for guinea pigs.

Consumption of chocolate means a boosted metabolic rate, and the heart pumping faster. For humans, this would be a nice kick in the morning, to start their day, but not so much for the piglet. It can kill them!

Excretory system problems

If you go through the ingredients, you would see phosphorous, and calcium.

This causes the formation of stones in the kidney, which will lead to a Urinary Tract Infection (UTI), urination with blood in it, and the process of urinating will be painful too. Over time, this will lead to kidney failure.

Would a vet recommend feeding Guinea Pigs chocolate?

The short and simple answer is no.

Like we mentioned, they might enjoy the treat, but it would almost immediately backfire, because they will start experiencing pain in the stomach, which would lead to nausea and even changes in stool. But that’s all on the surface, the real problem would begin internally.

Where issues such as heart failure, kidney failure, pre-mature death and even kidney stones are the probable and very likely to happen conditions. The vet would also recommend keeping the treat strictly for yourself, and so would we.

How much consumption of chocolate is recommended to feed Guinea pigs?

Not even an ounce of chocolate, because even that is lethal enough to kill them. If you go below that limit, that will cause illness to your pet, which will become worse over time, and death will still be the eventual end.

So, if you want your pet to live a long and healthy life, keep them away from junk food and snacks you snack on, while it may not be healthy for you, but it won’t kill you. Well, not immediately it won’t.

As far as the duration between feeding your piglet the chocolate goes, keep that to not even once in a blue moon, and we mean it.

Like we mentioned above, what you might think is little and won’t do any harm, will actually do more harm than you can imagine. So, it’s best to never feed them, ever.

What happens if a Guinea Pig eats too much chocolate?

The main substance that is toxic for guinea pigs is theobromine, and secondly caffeine. While you might enjoy the occasional cup of coffee, that could actually harm your piglet, because they don’t have a complex digestive system like we do.

And the immediate reaction after feeding them chocolate would be them feeling nauseous, they might even begin to pass unusual stool, and that would be coupled with an upset stomach, and an upset belly.

What happens next, is all internal. Since these toxic substances aren’t broken down, they start building toxicity inside. That means they can get heart failure, liver failure, kidney stones, and all that will lead up to one thing, that is death.

So, the process can be very slow, or painful, but the eventual end is the same, that ends in death for your beloved guinea pig.

What do you do if your Guinea Pig eats too much chocolate?

It will probably best to not leave your chocolate in a place where the guinea pig can attack on it. It depends on how much chocolate they have eaten.

It’s very rare for them to be okay after eating just a little, but we wouldn’t want to bank on those odds. There will still be stomach pain, and cramps that come with it too.

On the other hand, if the consumption of chocolate is large, then nausea, diarrhea and the guinea pig will have difficulty digesting anything else as well.

The best course of action would be to give them water and keep them hydrated, whilst you give them some veggies to keep the digestion process regulated. Check their stool and their general appearance and activeness, if you feel it’s not good, or not normal, then rush to your vet immediately.

Your Guinea Pig will start to show symptoms, and you would have to keep an eye out for the severity of them, and judge accordingly.
