Start with the established diagnosis
Pulmonary edema is fluid within lung tissue; pleural effusion is fluid in the chest cavity outside the lungs; ascites is abdominal fluid. Belly enlargement or weight change alone identifies neither fluid nor its cause. Use the diagnosis your clinician has established.

View the same day’s observations together
Put breathing, sleeping comfort, appetite, weight and belly appearance under the same date in the discharge plan. Weigh only when safe and comfortable, using the same scale; keep photo angles consistent. Do not press the belly to test for fluid or use its size to choose a dose.
- Weight loss does not necessarily mean improvement; the clinician also needs appetite and muscle-condition context. Avoid repeated handling of cats or small dogs for weighing; record “not measured” if unsafe.

Connect medication with drinking and urination
Record actual medication times, missed or vomited doses, and drinking/urination changes. Ask the prescribing clinic about a missed dose; do not double it, adjust diuretics or restrict water yourself. The clinician sets kidney and electrolyte recheck dates.

Hand over the trend; do not diagnose fluid
Report new breathing changes, appetite loss, weight or belly changes in a diagnosed heart patient promptly rather than waiting for the next appointment. Labored breathing, collapse or sudden hindlimb pain/weakness in a cat require immediate emergency contact.
- Lead the call with the diagnosis and the most important current change, then recent records and onset time. Bring medicine-label photos, discharge instructions and prior results. Confirm the next step, after-hours contact and changes that override the appointment date.

What changed
Replaced repeated respiratory warnings with diagnosed-patient trend handover, corrected fluid terms and medication boundaries in four languages.
Dates identify editorial updates and source checks, not clinical approval. All four languages were edited together; native-language and veterinary review remain pending.
