There isn't a standard size for young cougars as their size depends on factors like:
* Age: Kittens are obviously smaller than older cubs.
* Gender: Male cougars tend to be larger than females.
* Health: Well-nourished kittens will be bigger than those with limited food access.
However, here's a general idea:
* Newborn kittens: Weigh about 1-2 pounds and are about the size of a house cat.
* 6-month-old cubs: Can weigh around 30 pounds.
Adult cougars: For comparison, adult cougars can weigh anywhere from 80-220 pounds, with males being larger.
It's important to remember that cougars are wild animals and should be observed from a safe distance.
