How Do Cats and Dogs Drink Water?

The video explores the different drinking techniques of cats and dogs, highlighting the physics behind their methods. Cats use their tongues to create a column of liquid, retracting it quickly to drink without making a mess. Dogs, however, use a more forceful approach, splashing their tongues into the water to create a larger column, often resulting in a mess. The video also explains how humans and some animals use suction to drink, thanks to their complete cheeks, which allow them to create a partial vacuum.

What is the primary reason cats and dogs cannot use suction to drink liquids?

• They have incomplete cheeks.

• They lack adhesive forces.

• They have smaller tongues.

• They have weaker jaw muscles.

How do cats create a column of water to drink?

• By lowering their tongues deep into the water.

• By quickly retracting their tongues after touching the water surface.

• By curling their tongues into a ladle shape.

• By using suction like humans.

What role do adhesive and cohesive forces play in a cat's drinking technique?

• They allow the cat to create a vacuum.

• They help the cat's tongue stick to the water and each other.

• They help the cat's tongue curl into a ladle shape.

• They enable the cat to splash water.

How do dogs' drinking techniques differ from cats'?

• Dogs retract their tongues at slower speeds.

• Dogs have complete cheeks.

• Dogs use suction to drink.

• Dogs create a larger, messier water column.

What is the effect of a dog's tongue size on its drinking behavior?

• Larger tongues create larger splashes.

• Smaller tongues create larger splashes.

• Larger tongues create smaller splashes.

• Tongue size has no effect on drinking behavior.
