I realized that our lions and lionesses don't have much more information other than personality, age, gender, stats, and appearance. What if our lions/lionesses had other information such as height, weight, date of birth, etc? These could be added as a roleplay factor similar to personality. I often see people roleplay their lion as huge, (at least in lion standards,) which honestly isn't very realistic, since not every single lion can be gargatuan.

Weight could be factored by using a number generator when a cub is born and increase as they grow. For example, one cub could be born at 3 pounds (1.5 kilograms) then steadily increase. As an adult, they'd reach anywhere from 280 lbs (126.9 kg) to 418 lbs (189.6 kg) for males and 263 lbs (119.5 kg) to 395 lbs (179.2 kg) for females.

Height could be similarly generated and behave the same; males and females ranging from 3.5 - 4 feet tall (At the shoulder.) Both weight and height could be catagorized as Very Small, Small, Medium, Large, and Very Large, each size having their own range.

I can see how this wouldn't work out, but I personally think that this'd be a great idea for roleplaying!

Maulise suggested:

If the height/weight corresponded to how stats passed on or were gained in a minor way, at the very least (breeding stocky lions for greater strength, or lithe ones for speed). This would at least have the effect of being advantageous to stat breeders (since there are items that can boost speed or strength inheritance), and be a minor mechanic, rather than just flavour text....
