Brilliant
Brilliant to have on hand if you have a rabbit who won’t eat. I always keep this in my rabbit first aid kit.

Apple and banana flavour oxbow critical care
My guinea pigs prefer this to the aniseed flavour and I hardly ever struggle getting them to eat it. I've given if for post opp, or loss of weight, when they have diarrhea; it always helps balance their system as well as getting goodness into them. I highly recommend it, but I find this stuff is like gold dust, it sells out really quickly.

Essential for poorly guinea pigs
This product should be in every first aid kit for poorly pigs! Rolled into balls, on a spoon or syringe feeding, any way! The guinea pigs LOVE it, it smells ok (to a non-pig!) & is easy to use. It has been instrumental in saving my pigs life...Her weight was dropping & dropping until I introduced 2 hrly feeds...within 3 days her weight was up over 50gs! Keep it in the cupboard for when you need it!

A necessity for guinea pigs
My guinea pig loves this. I'm currently trying to get weight onto him in preparation for dental surgery and he is unable to chew hay. This is a life saver. I don't have to syringe feeding as he will happily eat this from his bowl. Definitely something that should be in every guinea pig medical box.

Saved my rabbit
My rabbit had a problem with gut problems last year and it cost me £600 to treat at the vet with all sorts of stuff. I couldn’t afford that this time, and was worried. I researched this and decided to try it. Well it worked. In fact it worked so well, and the flavour made it more palatable for my rabbit and wasn’t hard to get him to eat it. The only downfall is that it didn’t come with a syringe. This is a must have for rabbit owners, I’ve got some on standby and the first signs of any gut problems I’ll be using this straight away.

Much better than the original version
I’ve used critical care a few times over the years to help pull a poorly Guinea Pig back from the brink of death. It’s always been a bit of a struggle to get it into them as it smells very strongly of aniseed, which none of them seemed to have been keen on. However this one doesn’t have any of that smell and actually smells quite sweet. I’ve had no trouble at all getting my piggie to eat this and this is the one I will definitely be using from now on.

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.

This product is great for small pets such as rabbits, hamsters, guinea pigs, etc. Amazon was the only place I could find it at the time other than a vet hospital. This product is one I always keep on hand as a guinea pig mom. I no longer go without it. It’s essential during an emergency health situation with your small pet. I’d recommend every small pet owner have some on hand!
