A Complete Feeding Guide

You want your chinchilla to stay healthy, active, and thriving. One of the most important decisions you’ll make is choosing the right hay.

If you’re unsure which hay is best for your chinchilla, how much to feed, or which types to avoid, this guide covers everything you need to know.

Hay Is the Foundation of a Chinchilla’s Diet

Hay should make up 80–90% of your chinchilla’s diet.

Treats like dried fruit or vegetables may be offered occasionally, but hay must remain available at all times. Constant access supports digestion, dental health, and long-term wellbeing.

The safest and most commonly recommended hay types for chinchillas include:

  • Timothy hay

  • Orchard grass hay

  • Meadow hay

  • Botanical hay

What Hay Is Safe for Chinchillas?

Timothy Hay

Timothy hay is the most popular and widely recommended hay for chinchillas.

Benefits:

  • High fiber content

  • Moderate protein

  • Low fat

  • Supports digestive health

  • Naturally abrasive texture promotes dental wear

Because chinchillas’ teeth grow continuously, the crunch and fiber in Timothy hay help maintain proper tooth length.

Timothy Hay Cuts

Timothy hay comes in three cuts:

1st Cut

  • Highest fiber

  • More stems and seed heads

  • Lower protein and fat

2nd Cut

  • Balanced fiber and leaf content

  • Ideal for most adult chinchillas

  • Best overall choice

3rd Cut

  • Softer texture

  • Lower fiber

  • Suitable for younger, older, or dental-sensitive chinchillas

For most healthy adults, second cut Timothy hay is ideal.

Orchard Grass Hay

Orchard grass hay is softer than Timothy hay and easy to chew.

Benefits:

  • Good fiber content

  • Slightly higher protein

  • Supports digestive health

  • Useful for picky eaters or dental sensitivity

It is often used alongside Timothy hay for variety.

Meadow Hay

Meadow hay is a mix of grasses and dried plants.

Benefits:

  • Encourages natural foraging behavior

  • Provides dietary variety

  • Good fiber content

  • Promotes mental stimulation

Choosing organic meadow hay reduces pesticide exposure.

Botanical Hay

Botanical hay is typically a blend of grass hay mixed with dried herbs and flowers such as chamomile or rose petals.

Benefits:

  • High fiber

  • Encourages interest in eating

  • Provides aromatic enrichment

Because blends vary by supplier, nutritional values differ.

Benefits of Hay for Chinchillas

Digestive Health

Chinchillas rely on fiber for proper gut function.

  • Digestible fibers support energy and nutrient absorption

  • Indigestible fibers regulate stool consistency

  • Adequate fiber reduces risk of GI stasis and digestive upset

Dental Health

Chinchilla teeth grow continuously. Chewing fibrous hay naturally wears down teeth and prevents overgrowth.

Hay is their primary dental maintenance tool.

Mineral Balance

High-quality grass hay provides:

  • Potassium

  • Magnesium

  • Phosphorus

  • Calcium (in controlled amounts)

  • Protein

  • Fiber

Low calcium content is especially important for chinchillas.

Why Low Calcium Matters

Excess calcium can lead to bladder stones or kidney issues.

For this reason:

  • Limit alfalfa hay

  • Limit legume hays

  • Use grass hays as the primary diet

Which Hay Types Should Be Limited or Avoided?

Alfalfa Hay

High in calcium and protein.

Use only occasionally in very small amounts, if at all. Not suitable as a primary hay for adult chinchillas.

Legume Hays

Also high in calcium. Should be avoided or strictly limited.

Oat Hay

Oat hay is high in fiber and crunchy, which can support dental health.

However:

  • It is not ideal as a primary hay

  • Improper harvesting conditions may increase nitrate levels

Use cautiously and from reputable sources.

How to Store Hay Safely

To keep hay safe:

  • Store in a cool, dry place

  • Protect from moisture

  • Avoid mold exposure

  • Use breathable containers

Dusty or moldy hay should be discarded immediately.

Should You Rotate Hay Types?

Yes.

While Timothy hay should remain the staple, rotating small amounts of orchard or meadow hay adds enrichment and dietary variety.

Observe your chinchilla’s preferences and adjust accordingly.

How Much Hay Should You Feed?

Hay should be available 24/7.

As a rough guideline:

  • Several handfuls per day

  • Approximately 1–2 ounces daily

  • Unlimited grass hay access

You cannot overfeed grass hay in healthy chinchillas.

Is It Safe to Put Hay Directly in the Cage?

Yes.

Hay should always be accessible in your chinchilla’s enclosure. Use hay racks or feeders to reduce waste and contamination.

Conclusion

Hay is the cornerstone of a chinchilla’s diet. With 80–90% of their nutrition coming from high-quality grass hay, choosing the right type is essential.

For most chinchillas, second cut Timothy hay remains the best primary option. Supplementing with orchard grass or meadow hay adds variety and enrichment.

Providing unlimited access to clean, fresh hay is one of the most important steps you can take to support your chinchilla’s long-term health.
