A: A kitten is a baby cat. I would say that the kittens are about 2 weeks old, but they could be older. It takes about 2 weeks for a kitten to get its eyes open and start to use them, so they could have been born at or near 2 weeks of age, or even 3 weeks old. A few days after birth it will meow again for food and water. The more you feed your feline friend the more he wants to play with you!
