Can they be on CritCare for too long?

That is crappy! Sorry to hear you will be having trouble getting it, Sef.

Thanks. I bit the bullet and paid $26 for an unopened, small bag of Critical Care that was being sold on eBay. Free shipping, at least.

Sorry to hear that. I've always wondered if there is a way to use a high speed blender, coffee grinder or some other method to grind up hay and other foods that have the nutrients guinea pigs need into a fine powder to use in place of critical care. I haven't had the need to try it yet but if I need CC and can't get it, I'll have to. Is that something you can try?

I used a Ninja smoothie blender to make hay smoothies when Lacey was having trouble eating. I mixed hay, some shredded carrot, pellets, and water and whipped up mush. Then I kept a little fresh in the refrigerator, and froze dollops on parchment paper so I’d be able to thaw them out for her. The only problem is you don’t really know what the nutrients are, or how much to feed with the water mixed in.

I don’t think it will pulverize into powder. I needed to add water or the ingredients just sat in one place and didn’t blend.

That makes sense. It would take a very high speed grinder with very small blades to grind up dry ingredients, I'd imagine. As someone who likes to experiment, I might fool around with it and see what I can come up with. If all else fails, your method is sound and something I'd do if I had to hand feed and couldn't get CC.

I believe there are "burr" grinders that will pulverize items. I have a hand crank one that supposedly makes flour out of wheat berries - but it is mostly unused. Super fine grinds are needed for some coffees so it's possible one might find a machine that did a fair job on dry ingredients.

For a comparison between burr and blade grinders, check this out (quality burr grinders, more uniform, much more expensive):

For blade grinders, I ran across this extremely detailed review of blade spice grinders:

A burr grinder might work. I have one for my coffee beans and it pulverizes to espresso grind if it’s set fine enough.

My Jessie was on Critical Care for the last 5 years of her life as her only food source and for 12 months before that as a supplement! Use to blend rockmelon and red capsicum and add juice into dry mixture. She loved it and would let us know if we were 5 minutes late!
