Here's a breakdown:
* Under 8 weeks: A rabbit this young is considered a kit and should ideally stay with its mother.
* 8 weeks to 6 months: This is the juvenile stage where the rabbit is growing rapidly and developing its personality.
* 6 months and older: A rabbit this age is considered an adult.
However, it's important to note that these are general guidelines. The age at which a rabbit reaches sexual maturity and becomes fully grown can vary depending on its breed and other factors.
