How Rats Consume Water

Rats can consume water in two ways – direct and indirect means of consumption!

  • Direct water

Rats can get their water directly from sources such as puddles, streams, lakes, and other natural water sources in the wild.

In homes, wild mice and rats can get their water from the ones left behind in sinks, drains, condensation around pipes in the walls, or generally from overlooked sources of water such as pet water dishes.

  • Indirect water

Like it or not, rats can survive without directly consuming water for 3 weeks or more. They nourish their body with liquids derived from the food they eat as their way of hydrating themselves.

Even meals that are too dry for humans to warrant chasing it with one or two glasses of water will contain enough water to sustain rats or mice.
