I found this on another forum when I searched for undigested Phoenix worms in stool:

"Passing undigested PWs is an occurrence that happens occasionally. It's relatively rare but is seen more often in amphibians because they tend to not chew their food and they have very short digestive systems. Frog hobbyists and breeders tell us that they see this sometimes with other feeders. They suggest "pinning" the prey (pierce with a needle before serving) to allow digestive juices to easily penetrate which ensures complete digestion.

Breeders tell us that they do not view this as a problem--they compare it to humans finding undigested kernels of corn in the toilet bowl. The many reports of enhanced growth and improved health indicates that animals being fed PWs benefit from the superior nutrition the worms provide.

As long as my super friends are acting normal, I'm not going to worry about it. Someone left me some more worm poop today so hopefully they are all done!
