Some of the common ones include:

  • Dental Problems: Dental problems are one of the most common issues among guinea pigs that hinders their ability to eat and drink. Guinea pig molars generally grow inward, and it can harm their gums and chin when overgrown, thus making it difficult for them to ingest any food.

  • Gastrointestinal problems: Gastrointestinal problems like constipation, GI stasis, etc. can inevitably affect the food consumption of your guinea pigs. It can slow down the gut movement leading to loss of appetite in guinea pigs.

  • Temperature fluctuations: Temperature fluctuations can also affect the diet of your guinea pigs. A Guinea pig can get anxious and aggressive if the temperature goes beyond 25°C. Thus, make sure the temperature is well-maintained around your guinea pigs.
  • Recent Surgical Procedures: Surgical procedures can be painful for your guinea pigs. Your guinea pigs might experience pain for a few days after major surgery. Even minor surgery may leave them in mental stress affecting their food consumption. Make sure you consult with the vet if anything like this happens.

In many cases, it has been seen that the bottle nozzle doesn’t dispense water accurately, resulting in dehydration in guinea pigs. Sometimes mixing medicines or vitamin c drops can also change the taste of water in guinea pigs that they might not drink. This can further lead to dehydration and loss of appetite in guinea pigs.

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 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.

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.
