Fed my guinea pigs for years We've fed these Guinea Pig Pellets for over 5 years now, and I've always been extremely pleased with them. I occasionally run out and have to resort to using a popular recommended brand that can be easily purchased at the store, but my pigs definitely show their disapproval at this! The pellets are always fresh, smell great, and are pellets only. I've had a few bad experiences with other brands where I've found weird items such as rocks, sticks, and even plastic chunks in my pigs food. It's a bit disturbing as I demand only the best for my pigs and they deserve it. I've never had this issue with this brand, and this is why I am a repeat customer, and will be for as long as we have cavys.
