Review: A True Lifesaver for Small Herbivores — Worth Having on Hand - Oxbow Critical Care is one of those products I sincerely believe every rabbit, guinea pig, or small herbivore owner should keep in their emergency kit. When an animal isn’t eating on their own due to GI stasis, dental issues, illness, or post-surgical recovery, this can quite literally be a lifesaving product. The powder mixes easily with warm water to your desired consistency and works well for syringe feeding or bowl feeding. I appreciate that it’s timothy hay–based with essential vitamins and minerals, so it supports gut health while providing complete nutrition during recovery. The fiber content is exactly what you want when supporting a compromised digestive system. Palatability is also a big win here — even picky animals tend to accept it far better than expected, especially when warmed slightly or mixed to a smooth consistency. The resealable packaging helps keep it fresh, which is important since you may not use it daily. This is not meant to replace regular feeding long-term, but as a recovery or emergency support food, it’s unmatched. I’ve seen firsthand how valuable it is when time matters and an animal needs nutrition immediately Pros: High-quality, vet-recommended formula, easy to mix and syringe feed, supports digestive health, very appetizing to most small animals, essential to have on hand for emergencies, smells like a tropical green smoothie, large portions for the price, and varying hardness/thickness depending on the animals preference, and so much more! Cons: Should be fed as a directed and not as a daily food replacement, and hard to find in stock at times. Overall, Oxbow Critical Care absolutely earns its reputation. If you care for rabbits, guinea pigs, chinchillas, or other herbivores, this is a must-have product you’ll be grateful to have when you need it most. Highly recommended. 🐰💚
Review: Emergency kit must-have - As a rabbit owner, I always make sure to have this on hand for cases of GI stasis. I’ve needed to use this multiple times for my bunny, and it really is a lifesaver when your bunny is unable/unwilling to eat. It’s easy to mix up, and as long as you get a large enough syringe it’s fairly easy to administer. My rabbit loves all things Oxbow but doesn’t love this, I think because he associates it with force feeding. I have to hold him still and give this a little mouthful at a time, and while it’s super messy and tedious, it does what it needs to do. I would LOVE if Oxbow would sell this in smaller quantities, even single-serve packets. I tend to use fewer than five servings at a time when my rabbit has had bouts of stasis, and he needs this fewer than once a year, but the bag says to discard 30 days after opening. I have had to throw away multiple nearly-full bags of Critical Care after using just a few scoops, which is really wasteful. Tips: Make sure to put the syringe in the side of your animal’s mouth, not straight on, so they can swallow it themselves and it doesn’t get aspirated. Also, if your rabbit is not eating/pooping for 12 hours, get them to an emergency vet ASAP. If my rabbit is showing signs of stomach discomfort, I give simethicone first in case it’s gas, and this as a last resort before I call the emergency vet. There have been times when this got his stomach moving again, but if your rabbit has a blockage you don’t want to be forcing things into its stomach. I usually give it a few hours for this to help, and then it’s off to the vet. If you find your bunny needing this often, consider Oxbow’s digestive support treats. My rabbit goes crazy for those, and I really believe they are supporting his stomach health.

## Questions & Answers

**Q: What is the long term shelf life of this product (unmixed)?  I'd like to have some on hand in case of emergency.**
A: Basically you can keep it more than 12 months with no problem. My pet just got recovered of being with this amazing product, so... if I were you I would keep at least one in your house.

**Q: How long does this product stay good? Does keeping it in the refrigerator extend it's shelf-life? Thank you.**
A: Since this is a dehydrated product, I do not worry about shelf life.  As long as it remains dry, I believe it will be fine (will not spoil).  Some of the vitamins may loose potency, but other than that I believe It will be good for a long time.

**Q: Is this the anise flavored one?**
A: They no longer make the anise flavored one. They still did a year ago, but I bought more last week and wanted the anise flavored, but it's no  longer available. Now it's just apple-banana flavored, which is fine too.

**Q: can this be used as a hay replacer? if not what can be?**
A: I wouldn't recommend this as a daily hay replacer as hay is so important to a bunny.   Bunnies need to chew for digestion and to keep teeth from growing.   I would add this to his diet and still encourage him to eat hay.   As bunnies age they may have a problem with chewing due to dental issues.   This can be used to help with nutrition if that occurs.

### ⭐⭐⭐⭐⭐ Absolute must have for rabbits
*by A***K on October 28, 2025*

I’ve been running a rabbit rescue for a few years and this product has saved rabbit lives. Force feedings for rabbits with gastric stasis is always a pain, but this is the best product for it. Watering it down a little more than the instructions say is helpful for syringe feedings, following the instructions is fine if the rabbit can eat on its own. I would read and familiarize yourself with the ingredients on the back for educational purposes. For instance the use of papaya is for the proteolytic enzyme papain which helps break down proteins and fibers blocking the digestive tract. Similar to Bromelain in pineapple but with better efficacy further down the digestive tract which is where blockages normally occur. The rabbit in the photo is alive thanks to a combination of ringers and critical care. She got a hairball at the tail end of molting for the year even after brushing her coat.
