What is cat car?

As an AI language model, I do not have any information on a specific brand or model of "cat car." However, there is no such thing as a car built exclusively for cats. It is safe to assume that this term may refer to a car that belongs to a person who has a cat as a pet. Cats can be transported in cars using pet carriers or other forms of restraint for their safety and comfort while travelling. It is important to ensure that the cat is secured during the journey to prevent any accidents or injuries. Cats can also experience motion sickness in cars, so it is recommended to take necessary precautions to avoid this if the cat is prone to it.
