Guinea Pig Food Guide

Make hay the main meal

Fresh grass hay should be available all day. It keeps chewing normal, supports digestion, and gives guinea pigs something calm to do between meals. Pellets and vegetables should support the hay habit, not replace it.

Build vitamin C into the routine

Guinea pigs need a reliable vitamin C source because they cannot make enough on their own. Use a guinea-pig-specific pellet, safe vitamin-C-rich foods such as bell pepper, and a steady routine instead of guessing with random treats.

Measure plain pellets

Choose a plain guinea-pig pellet rather than a colorful mix with seeds, dried fruit, or crunchy extras. Measure the serving so hay stays interesting and body condition is easier to read.

Introduce greens slowly

Washed greens can be useful, but sudden changes can upset the gut. Add one food at a time, keep portions sensible, and use the food safety checker before offering herbs, fruit, or unfamiliar vegetables.

Treat appetite changes as urgent

A guinea pig that stops eating hay, leaves food, makes fewer droppings, loses weight, drools, or sits hunched needs fast help from an exotic-pet veterinarian. Do not wait days with a small herbivore that is not eating.

Check extras before they become habits

Use the food safety checker before a new vegetable, fruit, herb, or leftover salad piece interrupts hay eating or vitamin C planning. Keep the normal staple steady and test one change at a time.

Write notes beside the habitat: portion, water, stool or droppings, weight, cleaning changes, and behavior after the food. If appetite drops, diarrhea appears, breathing changes, or the animal seems painful, call an exotic-pet veterinarian instead of trying another treat.
