I didn't know what Red Wiggler was, so I had to Google it. :lol:PJM said:
If THIS is what you're referring to and if the nutritional analysis listed there is reliable, Red Wigglers contain:
- Moisture 84.8%
Protein 10:5%
Fat 2.0%
Ash 0.7%
Other 2.0%
Considering that typical high-quality low-fat dry cat foods recommended for hedgehogs contain about 28 to 32% crude protein at 10% moisture, which translates to protein 31 - 35% DMB, 69.0% DMB is way too high. (Btw, 2% fat at 84.8% moisture translates to fat 13.15% DMB, so it's not bad at all!)
Although there is no scientific proof presented, too much protein is generally considered to be very bad for hedgehogs (excessively rich foods cause stomach upset and often lead to kidney issues).
If you decide to feed Red Wigglers to your hedgie, I highly recommend you treat them as a very special treat which your hedgie gets only once in a blue moon.
