Who is lighter than a kitten? - in detail
To determine who or what is lighter than a kitten, it is essential to understand the average weight of a kitten. Typically, a newborn kitten weighs between 3 to 5 ounces (85 to 142 grams). As kittens grow, their weight increases, but for the purpose of this discussion, we will consider the weight range of a newborn kitten.
Several entities are significantly lighter than a kitten. These include:
-
Insects and Arachnids: Many insects and arachnids are considerably lighter than a kitten. For example, a housefly weighs approximately 0.035 ounces (1 gram), and a spider can weigh as little as 0.0007 ounces (0.02 grams).
-
Small Birds: Some of the smallest birds in the world, such as the bee hummingbird, weigh only about 0.056 ounces (1.6 grams). This makes them much lighter than even the lightest kittens.
-
Small Mammals: Certain small mammals, like the bumblebee bat, which is one of the smallest mammals, weigh around 0.056 ounces (1.6 grams). This is significantly lighter than a newborn kitten.
-
Reptiles and Amphibians: Small reptiles and amphibians, such as the tiny gecko or the paedophryne amauensis, one of the smallest frogs, can weigh as little as 0.0035 ounces (0.1 grams). These creatures are much lighter than a kitten.
-
Human Newborns: While human newborns typically weigh between 5.5 to 10 pounds (2.5 to 4.5 kilograms), there are cases of premature infants who weigh significantly less. Extremely premature babies can weigh as little as 1 pound (454 grams), making them lighter than a kitten.
-
Small Fish: Certain small fish, like the Paedocypris, one of the smallest vertebrates, can weigh as little as 0.00035 ounces (0.01 grams). These fish are much lighter than kittens.
Understanding the weight of these various creatures helps to illustrate just how lightweight a kitten is, even at birth. The entities listed above are all significantly lighter, showcasing the diversity of life forms that exist at the lower end of the weight spectrum.
