Timothy hay is the most important food a guinea pig eats. Here are the best hays we trust, and how to pick one.
Hay is about 80% of a guinea pig's diet and should be in front of them every hour of the day. It keeps their gut moving and wears down teeth that never stop growing, so it is the one thing worth getting right. Grass hays (Timothy, orchard, meadow) are what you want for adults. Here are the ones that are consistently fresh, green, and well-reviewed.
Our top pick. Consistently green, leafy and low-dust, and the easiest to find. A safe default for any adult guinea pig.
Check price on Amazon ›Often the freshest of the bunch if you want a step up, sold in bigger boxes that work out cheaper per pound.
Check price on Amazon ›A softer, sweeter grass hay. Great to mix in for picky eaters or anyone with a slight Timothy allergy (yours, not the pig's).
Check price on Amazon ›The budget option you will find in most stores. Fine in a pinch, just check for freshness and green color.
Check price on Amazon ›How to choose: look for green (not yellow/brown), a fresh smell, long strands, and minimal dust. Buy in bulk since they eat it daily, and store it somewhere dry and airy. Skip alfalfa for adults, it is too rich in calcium and is only for babies and pregnant pigs.
