The other creatures on the planet may have been bio-engineered in some fashion.

The planet was used as a massive research center. Only lately it was dedicated to the virus research.

Before then, they may have been experimenting with gene-splicing and biology optimization.

They may have engineered a lot of creatures to take in nutrients and maximize utilization.

What could also be occurring is vomiting. Some creatures eat, and after they digest the useful stuff they vomit up what they don't need. (this is often seen in very low-level creatures.. where they only have 1 hole to take in and excrete nutrients. As you go up the animal kingdom even rudimentary creatures have a mouth and a cloaca... eg: earth worms have a digestive tract.. food goes in, poo comes out.)

The bodies of the creatures may be engineered to be very efficient in catabolizing food (breaking it down) and metabolizing it for energy. So, there may be very little remaining of what they eat. They may have excretory mechanisms that are on the particulate level (microbioal), excreting waste out of their skin at such a microscopic scale you can't see it with the naked eye. Their body may convert waste byproducts to liquid and excrete it through pores.

That's sort of the issue with being stuck on a massive planet where super-advanced aliens had a research facility. God knows what creatures on the planet are natural and what are engineered. (The warpers are obviously engineered. But, it's unknown what else is engineered. And, if they were engineered long ago, given thousands of years to evolve they may have changed drastically from their original design as they optimized to fit into niches in the ecosystem.)
