Stop Wasting Time & Money On Bad Hay

Tired of wasting time picking through bad hay just to find the bits your rabbit, guinea pig, or chinchilla will actually eat?

  • We visually inspect and hand-pack every package of hay to ensure that you get fresh, green, fragrant hay of the highest quality.
  • Your hay is always hand-processed, never machine-cut, creating nice long strands and less small pieces.
  • You’ll no longer have to worry about your small pet suffering from irritated eyes or sneezing from excessive dust.
  • We preserve freshness by bagging all of our hay. This helps keep it from drying out or absorbing unwanted odors.

Why Hay Is Essential To A Small Pet Diet

Grass Hay is an important staple in the diet of rabbits, guinea pigs and chinchillas.

  • For rabbits 7 months and older and guinea pigs 6 months and older, grass hay should make up 80% of their diet.
  • For chinchillas older than a year, grass hay should make up 75% of their diet.

The constant foraging and grazing encouraged by hay helps to keep them physically active and mentally stimulated. It also helps to wear down their teeth while the long strand fiber helps to keep their digestion regular and functioning properly.

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

Small Pet's Guide to Hay Quality

Our Harvest Reports update yearly, and are a first glance and analysis of the newly harvested hay. This is what we are hoping (and anticipating) the rest of the year's hay will look like. Yet, nature's quirks make hay-growing and harvesting unique and can lead to a bit of unpredictability with every new batch of hay we receive. As new hay batches from this harvest comes in, typically every 4 to 6 weeks, we'll update you on any changes through our Fresh From The Hopper.

Quality changed

I’ve been using mountain grass for years. The last two orders were not that good. The quality changed a lot. It was long and not that dusty, but now its just to shredded and it’s making a HUGE mess and we are waisting too much. I have the subscribe option, but thinking about changing it. Did you change the product? Please help!!

Had to give the hay away

Short sticks & choppy, short hay. I’ve bought this mountain grass hay & at maybe 2 times it was very good. My bunnies loved it. The rest of purchases of this have not been good. I thought I’d try again since it had been awhile. My bunnies wouldn’t touch it. Poor quality. Gave the entire bag to my friend for her horses. My last attempt at this mountain grass!
