πŸ“ Summary

Cat distemper (panleukopenia) runs in stages β€” latent, then falling appetite, then vomiting and diarrhea with dehydration and fever, then a critical phase with watery stool and anemia. The key point: distemper is a viral gastroenteritis, far more dangerous than ordinary gut inflammation.

1 Stages of Distemper

The virus first hides in the airways and lymph, then invades gut and bone marrow with no clear signs. Early: dropping appetite and spirit. Mid: clear gut signs β€” vomiting, diarrhea, weakness; vomit turns from stomach fluid to yellow-green, more frequent; diarrhea worsens with dehydration and fever. Late: the make-or-break phase β€” temperature dips, gut signs worsen, frequent watery foul stool, dehydration, anemia. With active treatment, most that survive the first five critical days pull through.

2 Distemper vs. Gastroenteritis

Both show gut disease, but distemper is a viral gastroenteritis and much more perilous than gut inflammation from other causes.
