The Guinea Pig Diet

What should guinea pigs eat on a daily basis? When is the right time to give them food?

Let’s find out more about the diet of guinea pigs.

What Type of Food Should You Consider for Your GP’s Diet?

There are two things that every guinea pig owner needs to keep in mind when choosing food:

  1. Guinea pigs cannot produce Vitamin C, making them vulnerable to scurvy. Vitamin C should be included in guinea pig pellets to keep your pet healthy.
  1. Guinea pigs have constantly growing teeth. You should give your guinea pig something fibrous to chew on. Hay plays an important role here because the use of hard pellets alone will not solve the problem.

It is also important not to switch your guinea pigs’ diet too fast. If you need to do so, gradually switch the diet from their original home to their new diet.

When is The Best Time to Give Guinea Pigs Their Food?

Feed your guinea pig twice a day, in the morning and the evening.

The guinea pig will overeat if they are allowed to do so. Therefore, remove pelleted food that has not been eaten within one hour, and discard fresh fruits and vegetables that have not been consumed within 24 hours.

The guinea pig is primarily an herbivore, grazing on plants. Throughout the day, they munch on grass and vegetables. Fresh hay should be readily available at all times.

Moreover, guinea pig’s bowls should be emptied daily, then they should be cleaned and filled with fresh food and water.
