We’re not sure. The kitten is still very young, so we can’t say for certain why it may be acting this way, but there are a few things you can do to help. If your kitten is upset or restless during the day when left alone in her crate, try putting her on a calm food schedule and leaving the house only during light hours (about 6-8 PM). She will become more comfortable with being crated while you are gone if she knows that she will get fed at regular intervals. This also works well for feeding your cat/kitten throughout the day while keeping them happy and healthy!
