  • Natural variety — A genuine field blend of timothy, orchard grass, and brome, not mixed after harvest.
  • Hand-packed fresh — Packed by hand for fresh hay with minimal dust.
  • High fiber, naturally lower protein — Supports healthy digestion and steady weight in a grass-hay diet.
  • No herbicides or pesticides — Grown and harvested naturally.
  • Made for small herbivores — Rabbits, guinea pigs, chinchillas, and similar pets.
Ultra Premium Mountain Grass is a field blend of timothy hay, orchard grass, and brome—grown together and harvested as one crop, not mixed after the fact, for rabbits, guinea pigs, chinchillas, and other small herbivores.
No herbicides or pesticides are used—a genuinely natural, all-in-one hay with a variety of textures and colors in every batch.
Because it's field-grown, the exact ratio of the three grasses shifts a little by season and by bale. That's normal, and it's part of what gives pets the texture variety they'd naturally seek out.
We hand-pack every bag for freshness with minimal dust.

Harvest & Quality

Ultra Premium Mountain Grass is a field blend of timothy hay, orchard grass, and brome—grown together in the same meadow and harvested as one crop—for rabbits, guinea pigs, chinchillas, and other small herbivores.

Unlike a mixed hay, this blend isn't combined after harvest—it grows together naturally, with no herbicides or pesticides. That gives every batch some natural variation in texture and taste, closer to what a wild rabbit would actually forage.

Compared with our single-species hays, Mountain Grass offers more variety in one bag—a good rotation option alongside timothy or orchard grass.

Store hay in a cool, dry place with good airflow. A breathable bag or bin in a closet, pantry, or garage usually works well.

Avoid keeping hay sealed 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.

Keep grass hay available at all times. Most healthy adult herbivores can eat Mountain Grass free-choice alongside fresh water.

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.

When switching hays, mix the old and new hay over 7–14 days and watch appetite and droppings. Pellets and treats are supplemental.

We hand-pack every bag and inspect hay for freshness with minimal dust. Harvest reports give a season-level look at what we're sourcing; individual batches can vary as new hay arrives, typically every 4–6 weeks.

For batch-level updates, see Fresh From The Hopper. For the current Mountain Grass harvest report with analysis and photos, use the Mountain Grass harvest report link.

Small Pet's Guide to Hay Quality

Annual Harvest Report & Fresh From The Hopper - How's The Hay Looking?

Our harvest reports give a first look at each year's newly harvested mountain grass and what we expect from the rest of the season. Nature still shifts batch to batch, so color and texture can vary slightly between deliveries.

When new hay arrives, typically every 4–6 weeks, we share updates through Fresh From The Hopper. See the current Mountain Grass harvest report for analysis and photos.

Princess Cloud approves

My bun Cloud loves this hay. Its way fresher than I've ever bought from oxbow or kaytee brand. She hardly ate hay and when she did she picked at some pieces of timothy. We got a 2oz bag to try and she gobbled it up so fast so now we're sold!

Thrilled to hear Cloud is loving the Ultra Premium Mountain Grass! It's fantastic that she dove right in and gobbled it up. Knowing she's enjoying every bite makes us so happy! Thanks for giving us a try, and here's to many more happy munching sessions for Cloud!

Mountain grass hay

My one senior bunny is a very picky eater and I have found great success with the mountain grass hay. However, this last bag I ordered the hay is not like the previous bags. Hay is very thin and dry and she is not enjoying as much. Hope it is just a fluke.

Thank you for taking the time to leave a review for our Ultra Premium Mountain Grass hay. We're sorry to hear that your bunny is not enjoying the latest bag as much as previous ones. We understand how important it is for your furry friend to have high-quality hay. Mountain grass varies in its composition. The 2025 harvest has a good mixture of Brome, Orchard, and Timothy but that of coarse always varies by bale and this may be the reason for the difference you noticed in the hay's texture and your bunny's preference.

We apologize for any inconvenience this may have caused and hope your bunny will enjoy the next bag of Ultra Premium Mountain Grass hay. If you have any further concerns, please feel free to reach out to us. We're always happy to assist in any way we can.

Thank you for choosing our product and for being a valued customer.

My bunnies did not like this box of mountain

My bunnies did not like this box of mountain grass. They are not eating it. The previous box I ordered and received they loved and ate the mountain grass. Is this a different batch of mountain grass from previous order?

Thanks for sharing your experience, Anne. We're sorry to hear your bunnies aren't enjoying this box of Mountain Grass as much as the last one. We understand how frustrating it can be when their preferences change! While we always strive for consistency, as a natural product grown in mountain meadows, there can be slight variations between batches due to environmental factors. We want your bunnies to be happy! Please reach out to us at support@rabbitholehay.com so we can help find a solution for you and your furry friends.

My rabbit devours the mountain grass.

My rabbit devours the mountain grass!! He is extremely picky and was never a big hay eater - now I have to top off his hay throughout the day!! The mountain grass smells amazing and is fresh and clean. Light years ahead of Oxbow!!

My Guinea Pig loves it

My Guinea Pig loves it. I offer him regular Timothy Hay, soft kind I got here as well. The Mountain Grass is a different texture and he seems to love it as he goes back and forth between the two varieties.

Thrilled to hear your guinea pig is enjoying the variety, Linda! It's great that he loves switching between the Timothy Hay and the Mountain Grass. Keeping him happy and healthy with different textures is a wonderful way to provide enrichment. Thanks for sharing your experience!

My bunny loved this grass!

My bunny loved this grass and I bought the five-pound box after this. The hay was very green and fresh with very few brown pieces. I think this will be his new hay from now on.

That's fantastic! We're thrilled to hear that your bunny loved the Ultra Premium Mountain Grass and that you decided to go for the five-pound box. Fresh and green with minimal brown pieces is exactly what we aim for, so it's great to know we've hit the mark. Here's to many more happy binkies from your bunny!

My rabbits were exited to see I got them this hay again, they were starting to be picky with other hays but when I opened this bag, they immediately ran over to have some, it feels so soft and fresh and will be getting more for sure!

Too much powder, stems are short

Sorry but the grass/hay is way too powdery. I expected much better. I also don't like how you tape and plastic wrap boxes together - I need the skills of a surgeon to cut through your beloved plastic tape and free the boxes.

Gail
Thank you for sharing your experience. We're sorry to hear that the hay wasn't up to your expectations and that the packaging was difficult to open. Your feedback on the powdery texture and packaging is invaluable, and we'll definitely look into it. I will contact you via email to see if we can get this resolved for you.

Very delayed delivery. Why?

It took a very long time for my order to arrive. There was no tracking info for 6 days. It was supposed to be Fed Ex shipping. It was more like Turtle Express shipping! I sent an email requesting a refund. I was very disappointed and desperately in need of hay. So I placed an order with another company. Extremely disappointing!!
