Nobody talks about stage 4.

Time itself stopped in stage 4. All existence was unmade and remade. The cat who entered the yawn is not the same cat who emerged. This was done for the protection of reality from stage 3. Ask no further questions about stage 4 just be grateful.

Stage 4 is a howling feed-me-now-puny-hooman howl that escapes the blade hatch. Right before the mlem.
