Is it okay to play with my male cat until he is exhausted or ...
An adult breathes out approximately 400 grams (or 0.4 liters) of water vapor per day, while a child breathes out a similar amount relative to their size and activity level. A cat's moisture loss through breathing is less documented, but is likely lower than an adult human due to smaller size and lower respiratory rate, though it would still contribute to indoor humidity. 
Elaboration:
  • Adults:
    Adults lose around 0.4 liters (400 grams) of water vapor per day through respiration, with activity levels increasing this amount. A significant portion of this loss occurs during sleep, with one person adding about half a pint (approximately 285ml) to the air overnight. 
  • Children:
    Children's water loss through respiration is proportionally less than adults, but still significant relative to their smaller size. Infants have higher respiratory rates and a greater body surface area relative to their weight, leading to a higher water loss per kilogram of body weight. 
  • Cats:
    While there's less specific data on cats, they do lose water through respiration, similar to other mammals. However, their smaller size and lower metabolic rate would likely result in a lower overall water loss compared to adult humans. Their contribution to indoor humidity is still noticeable, especially in homes with multiple cats or during warmer months. 
Factors Affecting Water Loss:
  • Activity Level:
    Increased physical activity leads to higher respiratory rates and greater water loss. 
  • Ambient Temperature and Humidity:
    Lower temperatures and higher humidity can result in condensation, as the air's capacity to hold moisture decreases. 
  • Body Size and Metabolic Rate:
    Larger individuals with higher metabolic rates tend to lose more water through respiration. 

Cause

From each adult, child and pet. 1 litre per person, average. The same goes for a pet. 


Why It Matters

Moisture, mould and dust can affect asthma.

It is unsightly.
