Here are some potential features or aspects of a pet comb with steam functionality:

1. Gentle Detangling: The steam can help soften and relax knots and tangles in the pet's fur, making it easier and gentler to comb through without causing discomfort.

2. Hydration: Steam can add moisture to the pet's coat, which may be beneficial for dry or damaged fur, helping to improve its overall condition and appearance.

3. Cleaning: Steam may aid in cleaning the pet's fur by loosening dirt, debris, and excess oils, making it easier to remove during grooming.

4. Soothing: The warmth and moisture of the steam could have a soothing effect on the pet, particularly during grooming sessions, helping to relax them and make the experience more pleasant.

5. Portability and Safety: If such a product exists, it would need to be designed with pet safety in mind, ensuring that the steam temperature is safe for use on animals and that the device is easy to handle and operate without posing any risks of burns or injuries.

While the concept of a pet comb with steam sounds intriguing and potentially beneficial for grooming, it's essential to research any such products thoroughly and consider factors such as safety, effectiveness, and suitability for your pet's specific needs before making a purchase. Consulting with a veterinarian or professional groomer may also provide valuable insights and recommendations.
