Pet Polyuria/Polydipsia Symptom Guide | What to Watch For and When to Seek Veterinary Care
Understand possible causes of polyuria/polydipsia and key at-home observations
When polyuria or polydipsia occurs, closely observe and record drinking and urination changes. If it persists longer than 24-48 hours or worsens clearly, contact a veterinarian promptly.
What this symptom means clinically
Polyuria and polydipsia reflect abnormal body water balance or urine-concentrating function, possibly from reduced renal concentrating ability, insufficient antidiuretic hormone effect, or changes in blood osmolality. These changes increase urine volume and therefore drinking needs. Quantified drinking and urination data help distinguish persistent change from temporary physiologic response.
🐱 In cats
Cats often show thirst and urination changes subtly, so owners should watch for small changes in water intake or litter-box use.
🐶 In dogs
In dogs, changes in drinking and urination patterns are often easier to notice through outdoor trips or water intake, making trend records more direct.
