We think Pete may have been the runt of the litter. Not long after we got him from a shelter he started having digestive issues, and was so thin he seemed like just a spinal cord. I brought him to the vet twice, and she did tests that she was surprised showed no illnesses. She recommended this product, and Pete likes it and gradually got up to a normal weight with no ongoing health issues. I still give it to him daily, to play it safe. When he was sick it was just Timothy hay and this product.

Essential Guinea Pig Supply!

If you have a guinea pig at all, this is essential to keep on hand for when they will, inevitably, become sick or depressed and refuse to eat. Administering this

If you have a guinea pig at all, this is essential to keep on hand for when they will, inevitably, become sick or depressed and refuse to eat. Administering this when my piggies have been ill has literally save their life and kept them from going into GI stasis (I'm not a veterinarian, so this is not medical advice). As someone who had a guinea pig on death's door, I'm so very glad that I had a bag of this in the freezer on the advice of my vet and was able to give it to him to save him. We always keep a bag on hand and like I said, you can put it in the freezer so it lasts longer.

Critical Care dietary supplement

Tortoises in crisis who need to be stomach tube fed especially, benefit greatly from this type of powder. Those that come to me weak and nutritionally deprived

Tortoises in crisis who need to be stomach tube fed especially, benefit greatly from this type of powder. Those that come to me weak and nutritionally deprived but are able to nibble also benefit because I can top dress it on what I feed them, so they have additional, more natural food to help boost their health.

My bunny had stopped pooping for 12 hrs and I had this on hand. Let me tell you she pooped and was much better. I love having this for those kinds of moments, because you never know. There was no need to take her to the vet because she went back to her usual self/habits.

Great recovery food

Great to have on hand for digestive emergency. Mixes easily with warm water and very smooth for syringe feeding. My guinea pig will eat it from a bowl!

I keep Critical Care Herbivore in the Anise flavor in stock at my house because it is the only flavor my rabbit will readily eat. She really used to fight me feeding Critical Care in the other flavors. Find out which flavor works for your bun! With this flavor, she will eat it out a syringe on the floor without a problem.

I've given Critical Care to our senior bun many times after dental surgeries, when he wouldn't eat on his own. Grateful for a product like this that helps our babies
