Why is my 2-month kitten sleeping all day?

Kittens, especially young ones like your 2-month-old, need a lot of sleep to grow and develop properly. It's normal for them to sleep for up to 20 hours a day. This helps them conserve energy and allows their bodies to focus on important processes like digestion and growth. If your kitten is eating, playing, and using the litter box normally when awake, there is likely no cause for concern. However, if you notice any changes in behavior or if your kitten seems lethargic or unwell, it's best to consult a veterinarian.
