"Normally, guinea pigs are super picky about what they eat. I hate a previous guinea pig before I got two new ones and she hated almost everything I bought for her. She didn't like oranges but she loved strawberries and spinach and she loved sunflower seeds. With this product, she didn't reallylike but with my two new guinea pigs, they really love this stuff and it is made with timothy hay which is good. My new guinea pigs are not so fond of sunflower seeds and pumpkin seeds so any other mixes, I don't really buy because when I give them that product they really leave a lot left over such as the corn kernels. So, basically if you're looking for food for your guinea pigs, you should definitely buy something they're used to by asking the previous owner, seller, or breeder. And if you want to change the food, then slowly integrate the new food with the old food and they may bound to change unless they're super picky, then... you may just have to stick to what they're used to."
