What counts as “drinking more”?
Absolute volume is difficult to judge in multi-cat homes, so look for trends: more frequent drinking, emptying bowls faster, drinking from unusual places, larger litter clumps or urinating more often.
Common causes
Kidney disease, diabetes mellitus, hyperthyroidism and some medications are important causes. Less common endocrine, liver or electrolyte problems may also increase thirst and urination.
What should I track?
- Body weight
- Appetite
- Urine-clump size and frequency
- Vomiting or diarrhea
- Activity level
- Medication changes
What tests may be recommended?
Bloodwork and urinalysis are common starting points. Depending on age and findings, blood pressure, thyroid testing, urine culture or imaging may be appropriate.
