Depends on the species. A few can run, hunt, and keep up with the group within hours of birth. Some, like marsupials, are born blind, deaf, with an inability to swallow unaided, looking like weird larvae, and must live in their mother's pockets until they can handle anything. People and cats are like marsupials.
As cats get older, their parents teach them survival skills (by showing interest in certain activities that the kittens imitate, not through more explicit instruction; there are cat studies that show this.) It takes kittens probably a year to mostly learn how to be cats. As people get older, we shove a summary and guide to 3000 years of written and tested guidance into them and show them how to brush their teeth properly. It takes about 15 years.
No big difference between humans and animals here.
