Tammy Wornow –
Great product.
Great source of vitamin c for Guinea pigs. Oxbow is awesome. My Winston would starve without Oxbow foraging food adult Guinea pig for and he love all the oxbow biscuit treat such as this one. Thank you Amazon for offering some many Oxbow products.

Guinea pig loved them
Bought these to add more vitamin C into my gp diet. He loved his cookies. They were great quality and easy to digest. Unfortunately at over 8 years old, he was in his last months and passed a couple of weeks ago. He enjoyed them right up to the day before. I would definitely buy them again.

Just what I needed!
I’ve been looking for these for FOREVER. My local pet stores were out of stock of these for the longest time so I had to resort to liquid vitamin C. Long story short I’ve ordered a couple of the largest bags in hopes that I’ll have some for awhile in case this happens again! My piggies love these, easily able to break into 2 pieces, and definitely worth the price.

My 3 guinea pigs love these
My guinea pigs are picky. Oxbow is a preferred supplier of food and vitamin treats to my girls, they go crazy when they hear the sound of the bag. These chewable hay and Vitamin C supplements are hard and good for keeping their “filed” down.

Popular with my piggies!
Very popular with my piggies and they are almost all whole…very few broken, if any.

Vitamin c is important for guinea pigs
My piggies didn’t like them. They only ate them once in awhile. They’re kind of way too hard
Frank –
YUM!
The Guinea Pigs are addicted to this. They will fling carrots and strawberries away for these.
Kristi –
Saved my guinea pigs
Saved my guinea pigs from starvation. But seriously, this is a daily treat for them and they have come to expect it so when oxbow was having issues, I thankfully found it here. Hopefully it’ll all get back to normal but until then, I know where to look.
