Feline pyometra (uterine infection)
Emergency — go nowA post-heat emergency of unspayed females, often better hidden than in dogs (cats lick away discharge). Thirst + lethargy + a changing belly deserves high suspicion; surgery is the cure.

Can I monitor at home first? What should I watch?
If energy and appetite are normal with no other signs, 24-48 hours of monitoring is reasonable. Keep notes on frequency, duration, appetite, water intake, energy and what the stool/urine looks like — vets find this very useful.
What should I prepare before the clinic?
Note when the symptom started and how it changed; bring packaging or residue if ingestion is suspected; bring vaccination and deworming records; and if possible take a video (odd gait, cough sound) — clearer than describing.
