My guinea pigs won’t eat the hay.

There are a couple reasons your guinea pigs may not want to eat hay.

1. There’s a chance it’s the type of hay. If they’re not eating the Timothy Hay, try feeding them Orchard Hay and vice versa.
2. Monitor the amount of pellets you’re feeding your guinea pigs, and make sure they’re not filling up on too much of those or too much of their fruits and vegetables.
