Adult Guinea Pig
My pigs love the Naturals range but it's quite expensive so I've looked into healthy treats I can buy in bulk to save money. These are all fine to give to your pigs.

- Bran - buy it at health food stores such as Holland Barratt
- Oats - buy the cheapest own-brand from a supermarket, or in a large bay from a horse feed shop
- Barley rings - buy from a horse feed shop
- Goat mix (consits of pellets, oats etc) - buy from a horse/farm feed shop, or it is available from UK pet shop Just For Pets
- Grass - It sounds obvious but many of us have limited amount of grass. Buy 'Just Grass' from a horse feed shop in a large bale!
