How to store it

Let everything cool completely before you pack it away, since trapped steam causes sogginess and mold. Keep it at room temperature for up to 2 weeks, or in the fridge for up to 4 weeks. If anything smells off or shows mold, throw it out.

Feeding tips for guinea pigs

Guinea pigs need vitamin C every day and plenty of hay to keep their teeth worn down. Introduce new vegetables one at a time and watch for loose stools. Wash produce well and serve it fresh, removing anything uneaten after a few hours. Guinea pigs are social, so most owners keep two or more, and portions here assume one animal.

Make it ahead

To save time, measure and prep the ingredients the day before and keep them covered in the fridge. Label containers with the recipe name and date so you always know what to use first. Most of the work in this recipe is hands-off, so it fits easily around a busy week.

What to watch for

Loose stools usually mean too much fruit or a new vegetable introduced too fast. Cloudy or gritty urine can be a sign of too much calcium. Signs of vitamin C deficiency include a rough coat, sore joints and reluctance to move. See an exotics vet if your guinea pig stops eating.

Shopping list

Before you start, check that you have guinea pig pellets, timothy hay, carrot and water. Most of it is at the grocery store; hay, pellets, feed and supplements are at pet or feed stores. Buy fresh produce close to the day you cook.

Safety notes

Carrot: Sugary, so a few times a week only. Never add onion, garlic, chocolate, grapes, raisins, xylitol or salt, and check the safety guide before trying a new ingredient with your guinea pig. This recipe is general information, not veterinary advice.
