When Is a Kitten Full Grown?

A kitten is considered fully grown between 1 and 2 years of age, although some breeds, such as the Maine coon, can take longer to develop. Due to how early cats become sexually potent, it is recommended to spay or neuter the cat between 3 and 6 months of age.

The house cat is a small, predatory animal that is believed to have been first domesticated in ancient Egypt. Cats have excellent night vision and are capable of hearing sounds either too faint or too high in frequency for human ears. This is for detecting the noises of small prey, such as field mice.
