Estimate how much water a cat should drink each day.
A typical cat needs about forty milliliters of water per kilogram daily, adjusted for heat and activity. Cats on wet food get much of this from their meals. Felines drink less than ideal by nature, so monitoring intake helps catch reduced drinking that can point to kidney or urinary issues.
