Our verdict
Why hay is the diet, not a side
Rabbit and guinea pig physiology runs on continuous fiber: teeth that grow for life need constant grinding, and guts evolved for grass need constant throughput. Hay isn't the garnish on pellets — it's the meal, ideally 80%+ of intake for adults. Quality matters because a hay they won't eat is nutritionally identical to no hay.
The Oxbow difference, practically
Small-pet hay is a freshness product. Oxbow's farm-to-bag control shows up in the two markers owners actually check: green color and grassy smell. Consistency is the quieter advantage — the picky guinea pig who rejects one brand's brown batches usually commits to this one.
Alfalfa confusion, cleared
Adult rabbits and guinea pigs need grass hay (timothy, orchard, meadow). Alfalfa is legume hay — richer, calcium-heavy, right for growing juveniles and pregnant does, wrong for healthy adults as a staple. This is timothy, which is the point.
What owners say
Summary of recurring themes in verified owner reviews, paraphrased from our research — not quotes or counts.
Praise: picky-eater acceptance is the theme — guinea pigs and rabbits that selectively starve themselves through mediocre hay commit immediately. Freshness on arrival gets verified in most accounts.
Complaints: price per pound versus farm bales, occasional compressed packing, and the odd batch that divides opinion on cut coarseness.
