What Do Chinchillas Eat

Introduction

Understanding what chinchillas eat is essential for keeping them healthy. Chinchillas have one of the most sensitive digestive systems of any small pet — their diet must be high in fiber, low in sugar, and very low in moisture. Here's a complete breakdown of what chinchillas eat and what to avoid.

What Chinchillas Eat in the Wild

Wild chinchillas in the Andes mountains of South America eat a sparse, dry diet of grasses, plant stems, bark, leaves, and seeds. Their digestive systems are adapted for this tough, fibrous, low-moisture diet. This is why fresh fruits and vegetables — which are high in moisture and sugar — can cause serious digestive problems in pet chinchillas.

Timothy Hay — The Foundation (70–80% of Diet)

Hay is the most important food for chinchillas and must be available 24/7. It provides the long-strand fiber that keeps the digestive system moving and wears down continuously growing teeth. Oxbow Orchard Grass Hay is an excellent everyday choice. Kaytee Timothy Hay Blend Cubes can be offered as an enriching supplement. Use a hay feeder rack to keep hay fresh and accessible.

Pellets — Concentrated Nutrition

Quality chinchilla pellets provide vitamins and minerals that may be lacking in hay alone. Feed 1–2 tablespoons per chinchilla per day. Choose a plain, timothy-based pellet without seeds, nuts, or dried fruit. Use stainless steel feeding cups to keep pellets off the cage floor.

Safe Treats — Very Sparingly

Treats must be given extremely sparingly due to chinchillas' sensitivity to sugar. Safe options include:

• VESPRO Timothy Hay Sticks — hay-based, low sugar, supports dental health
• Oxbow Organic Rewards Barley and Hay Biscuits — healthy, low-sugar biscuit treats
• Dried rosehip — a traditional chinchilla treat; offer 1–2 per week maximum
• Dried herbs (no added sugar) — chamomile, rose petals, lavender in tiny amounts
• Apple wood chew sticks — for chewing enrichment and dental health

Water

Fresh water must always be available via a no-drip water bottle. Change daily and clean the bottle weekly. Chinchillas drink less than guinea pigs but still need constant access to clean water.

What Chinchillas Cannot Eat

• Fresh fruits and vegetables — Too high in moisture and sugar; causes diarrhea and GI upset
• Raisins — Extremely high in sugar; a common cause of chinchilla diabetes
• Yogurt drops and honey treats — Far too high in sugar
• Nuts and seeds — Too high in fat
• Corn — Too starchy
• Avocado, onion, garlic — Toxic
• Chocolate and caffeine — Toxic
• Iceberg lettuce — Too high in moisture; causes diarrhea

The Golden Rule

If it's moist, sweet, or high in fat — chinchillas shouldn't eat it. Their digestive systems are designed for dry, fibrous food. When in doubt, stick to hay, pellets, and water.

Conclusion

Chinchillas eat a simple, strict diet of unlimited timothy hay, measured pellets, fresh water, and minimal dry treats. This simplicity is actually a strength — a chinchilla fed correctly will have excellent digestive health, beautiful fur, and healthy teeth throughout their long life.
