Ultra Premium Mountain Grass

Mountain Grass is a true field blend of timothy hay, orchard grass, and brome, grown together in the same meadow rather than mixed after harvest.

That gives every batch some natural variation in texture and taste—closer to what a wild rabbit would actually forage across a season.

No herbicides or pesticides are used on these fields, so it's a genuinely natural product from start to finish.

For adult rabbits 7 months and older and guinea pigs 6 months and older, grass hay should make up at least 80% of the diet. For chinchillas older than 1 year, aim for at least 75% grass hay.

Younger animals, nursing mothers, and pets with health concerns may need different portions. Check with your vet if you're unsure.

Mix the new hay with the old hay over 7–14 days so the change is gradual.

Watch appetite and droppings during the switch. If your pet stops eating or stool looks unusual, slow the transition and contact your vet.

Store hay in a cool, dry place with good airflow—a breathable bag or bin works well.

Avoid sealing hay in plastic long-term; trapped moisture can lead to mold. If hay smells musty, feels damp, or looks unusually dusty or discolored, discard it and open a fresh bag.

Commercial hay from a trusted producer is very low risk for RHDV2, and we monitor official reporting for the regions where we source and pack hay.

We source in Northern California, where there have been no reported RHDV2 cases in our sourcing and warehouse areas to date. Current inventory is from the 2025–2026 growing season in that region. USDA guidance suggests dried virus may remain stable about three months; we follow harvest timing, storage, and handling with that in mind.

For symptoms, vaccines, maps, and what we watch ongoing, see our RHDV2 information hub and the RHDV2 section of our FAQ.

Yes, that's normal. Since Mountain Grass is field-grown rather than mixed, some batches lean more toward timothy, others more toward brome or orchard grass.

It's a sign the hay is genuinely field-blended, not a quality issue. See the current Mountain Grass harvest report for what this season's mix looks like.
