How Much Hay Does a Guinea Pig Eat a Day?
Guinea pigs should eat unlimited hay, roughly a pile as big as their body every day. Learn how much to offer and how to reduce waste.
Rule of thumb
Offer unlimited grass hay. Many owners use a guide of a pile at least the size of each pig's body every day, topped up so it never runs out.
Why so much
- Keeps teeth worn down.
- Keeps the gut moving.
- Provides most of the fiber in the diet.
Reduce waste
- Use hay racks or bags plus a loose pile.
- Offer smaller amounts more often.
- Store hay dry and ventilated.
Which hay
Timothy, orchard grass and meadow hay suit adults. Alfalfa is rich in calcium and better reserved for young, pregnant or underweight pigs on vet advice.
