It’s fine if your rabbit eats small amounts of guinea pig food, but make sure that you don’t make it a habit.

Rabbits and guinea pigs have different nutritional needs.

As an example, rabbits can make their own vitamin C while guinea pigs can’t, which is why most guinea pig foods are loaded with vitamin C.

Feeding large amounts of food that contains vitamin C to rabbits can lead to kidney damage.

Now that I’ve given you the gist of the article, read on as I explain in more detail why rabbits can’t eat guinea pig food:

Risk of feeding guinea pig food to rabbits.

Rabbits and guinea pigs have different nutritional needs, feeding your rabbits guinea pig foods has risks if fed long term.

Here are some of the risks associated with feeding your rabbits large amounts of guinea pig food:

Kidney damage

Excess vitamin C in rabbits is shown to be converted to oxalates, which in turn may trigger the formation of kidney stones.

Rabbits are already making their own vitamin C, feeding high amounts of additional vitamin C, like what guinea pig food has, can lead to the formation of kidney stones if fed long term.

Here are the signs that your rabbit might be suffering from kidney stones caused by excess vitamin C:

  • Blood in the urine (hematuria)
  • Thick, pasty, cloudy, or beige-to-brown-colored urine.
  • Urine staining in the area between the anus and genitals.
  • Straining or pain during urination.

Diarrhea

Diarrhea in rabbits is often caused by the wrong diet or when the diet is changed too fast. 

Feeding your rabbit large amounts of guinea pig food would check those two boxes I mentioned.
