Beginner friendly: Moderate

I’d rate it a 3 because pet boarding requires some initial setup, such as creating a safe and comfortable environment for pets, understanding basic pet care, and possibly obtaining necessary licenses or insurance. While it doesn't require specialized skills, it does demand time, effort, and a genuine love for animals. Building a client base can take time, but platforms like Rover or word-of-mouth can help. It's moderately easy to start earning once these elements are in place.
