In many cases, it has been seen that the bottle nozzle doesn’t dispense water accurately, resulting in dehydration in guinea pigs.

If your guinea pig is not eating and moving, then it definitely means there is something wrong with them.

It could be a severe health issue like dental problems, liver or kidney disease, or something even more critical.

It seems like they are weak and unable to move due to the lack of nutrition in their body.

Thus, you should make sure you take them to a vet immediately. The vet may ask for blood tests and radiographs.

The treatment can include:

  • Antibiotics
  • Critical care feeding for a few days

And in the meantime(until the vet is available), you could encourage them to drink some water and offer them food or critical care to keep their digestive system going.

You don’t want to completely halt their gut movement as the results could be catastrophic.

Guinea pig not eating or pooping

If your guinea pig is not eating or pooping, then it clearly indicates there is a blockage of poop in their gut, or the gut movement have slowed down.

There can be a lot of reasons behind the same.

A frequent diet change, improper diet, or some other health issues like GI Stasis could be the possible reason behind it.

You must weigh your guinea pigs to see if they are losing weight. Taking them to a vet immediately is essential.

Your vet needs to do some x-ray and radiotherapy to find the possible blockage and treat it accordingly.

The treatment include:

  • Ranitidine, and Metacam every 24 hours
  • Buprenex, and Reglan every 12 hours
  • Critical Care- 4 ml 4-5 times a day.
  • Once appetite and poo becomes regular they need to be followed up by Cisapride and Meloxicam orally.

You should keep feeding them critical care to keep something going into their gut.

Guinea pigs can’t survive long without food. Thus, immediate action is required.

Never try to tree such medical conditions at home as it can be life-threatening for your guinea pigs.

Guinea pig not eating and hiding

If you have just bought a new guinea pig home or you have moved your guinea pigs from one place to another that is entirely new for them, then chances are they are scared and feeling insecure.

Fear and anxiety could be a significant factor that affects our guinea pig’s diet. If you have a good bond with your guinea pigs, try to calm them down by petting them and hand-feeding them their favorite treat.

If you have just bought a new guinea pig home, provide them with some hiding space, and sit beside them and talk to them for some time.

This should calm them down and encourage them to come out, explore, and have their food.

You should also enquire about the previous owner for their diet and continue the same for some time so your guinea pigs could get accustomed to the new living environment more easily.

Guinea pig not eating and losing weight

Guinea pig not eating and losing weight

If your guinea pig is not eating for a while, then the weight loss is directly related to their appetite.

If your guinea pig is not eating their food correctly, then they are going to lose weight ultimately.

There could be a lot of health problems that are leading to loss of appetite in your guinea pigs. Some of the common ones include:

  • Dental problems
  • Respiratory and urinary infection
  • Poor quality food

You need to look out for the possible cause and book the vet appointment immediately.

Keep feeding some critical care by syringe until you can reach the vet.

A significant weight loss can be fatal for your guinea pigs and directly implies that your guinea pigs need some nutrients immediately.

Guinea pig not eating hay or pellets or veggies

Guinea pigs are picky eaters, and some guinea pigs might not like a particular brand of hay or pellets. The same applies for veggies as well.

While some guinea pigs love Bell Peppers, others might not touch it. You need to experiment and find out what your guinea pigs like and serve the food accordingly.

If you bought a new bag of pellets or hay and your guinea pig doesn’t like it, then you might need to give it away to someone else and get the brand your guinea pigs prefer.

There is no way to force-feed your guinea pigs. Please make sure you always have some food in your hand for your guinea pigs.

I prefer to buy a new bag a few weeks early and switch the diet slowly to get my guinea pigs used to the new food.

If they still don’t like it, then there isn’t much we can do about it.

For vegetables, I would try a different vegetable, and soon you will learn what your guinea pigs enjoy and what they don’t. Make a diet plan for your guinea pigs accordingly.

Guinea pig not eating after surgery

Hormonal imbalance in guinea pigs

Guinea pigs can go through a lot of pain and stress if they have been operated recently.

It could be a minor surgery or a major one, but the effect of the same could be seen in your guinea pig’s diet and behavior for a few days.

Apart from the mental trauma, the antibiotics prescribed could also harm our guinea pigs diet as they might not feel hungry even if their body lacks nutrients.

Thus, providing them with critical care and supplements for a few days by syringe feeding them is crucial for their well being.

Your vet may prescribe some pain medicines as well after any major surgery.

Guinea pig not eating breathing heavy

If your guinea pig is not eating but breathing heavily, then it clearly indicates there is some health problem.

Some of the common issues could be an allergy from the food like hay or pellet, or it could be something worse like an upper respiratory infection.

Whatever is the case, you need to look out for further symptoms and try to syringe feed them at the same time.

If they are not eating for some time now, then their health condition could be deteriorating, and you must seek medical assistance immediately.

A lack of proper health checkup and treatment can lead to serious health issues in the future.

Syringe-feeding your guinea pigs

Syringe-feeding your guinea pigs

Sometimes syringe feeding can be the only choice to help our guinea pigs recover.

Yes, it is not something that any guinea pig owners would like to experience, but the fact is there is going to be a situation like this at some point, and you must be prepared for the same.

So, here are the steps you need to follow to syringe feed your guinea pigs:

  • Get a syringe of appropriate size(5ml-50ml). Get the bigger one as it is easier to work with. I personally love the curved dental syringe, as it makes feeding a lot easier. Chop the ends off using a scissor and make sure to sand out any edges.
  • Take some Oxbow’s Critical Care, Sherwood digestive support, or you can mix ground up pellets with fresh greens, any vegetable baby foods, etc. and mix them with some water. You can also add some liquid vitamin c supplement in the mixture.
  • Fill the syringe and bring the tip into your guinea pig’s mouth behind their front incisors and slowly depress the plunger. Give your guinea pigs some time to swallow.
  • You need to feed the mixture every 2-3 hours to ensure your guinea pigs get their gut movement going. It also provides them with enough strength to recover.
  • If, after feeding it for a couple of times, your guinea pig is still not moving much, then encourage some movement for at least 10–15 minutes every 6–8 hours, as activity promotes gut movement.

Can guinea pigs die from not eating?

Yes, guinea pigs can die from not eating food for more than 24-48 hours.

Guinea pigs need to be continually eating something to get their gut moving.

If your guinea pigs don’t eat for a few hours, their digestive system will slow down. In less than 24 hours, the system can completely stop processing and result in GI stasis in your guinea pigs.

Your guinea pig will also start losing their weight quickly, and by the time you might realize what’s happening, it can be too late, and they might even lose their lives.

It is crucial to get your guinea pigs to a vet if they stopped eating for more than 6 hours.
