Questions & Answers

11 Customer Questions

How long is the shelf life of these multivitamin treats once the package has been opened? Will they loose their potency over time?
Answer by ChewyNov 26, 2018
The “Best By” date on the back of the package refers to the shelf-life of an unopened product. Once the supplement is opened, the product is best used within 60 days. Any oxygen the product is exposed to once the package has been opened will lead to vitamin degradation over time, but studies have repeatedly shown the product’s vitamin content is stable for a full 60 days. It is important to squeeze as much air out of the package as possible and seal the top between uses.

Can these be given to squirrels?
Answer by ChewyJan 09, 2020
Oxbow Natural Science Multi-Vitamin Small Animal Supplement is nutritionally appropriate for squirrels, with the appropriate dose being ¼ tablet daily.

Would it be okay to give these alongside Oxbow Natural Science vitamin C tablets?
Answer by ChewyJul 05, 2021
There is L-Ascorbyl-2-Monophosphate (Vitamin C) in this product. We encourage speaking with your Veterinarian before combining supplements, for the safest opinion.

are these healthy for ferrets?
Answer by ChewyApr 21, 2021

Great product!

I got these to help my little rabbit that was on week three of GI Stasis treatment. She had lost almost a pound and I wanted to make sure she was getting in vitamins she was missing from her pellets. At first she wouldn’t eat these so we crushed it and mixed it with her Critical Care. As she improved, she would eat it if it was soaked in pineapple juice. Now that she is almost back to 100% she just eats one a day like a treat. I can’t say whether or not these made a difference but she’s in good health now and this was part of her treatment plan. I will always have these on hand.

Not recommended for hamsters

I bought these for my Syrian Hamster to keep him healthy. Unfortunately, he refuses to eat them. He won't even take a nibble of it. So I wouldn't recommend these for hamsters.

My guinea pig loves these! It’s always easy to get him to take this vitamin and Oxbow’s Vitamin C. He’ll even whistle for them!

Happy Chin

My little boy LOVES these!! He's always excited when he hears the bag open. He thinks it's a treat. I like that there is a line down the middle of them that makes it easier to split them in half for him.

Best treat ever, and Bunn doesn't know it's good for him

My bunny BEGS for treats all the time and I worry about his diet because I am such a pushover for that FACE. I bought the Oxbow vitamins thinking HE will think they are the daily treat and he LOVES them. I break them in half so he gets 2 under his forage cups to find.

Vitamins are Grrreat

Always gave, & give vitamins to my pets! Saw that in my fish their scales and finds were brighter in color, & they lived longer. Therefore the same should apply to my Fergus! He's 10 going on 11 this October!
