I can understand why people think it's easy to make money off of snakes compared to other animals. Even low-mid tier ball python hatchlings can easily sell for $200-300 each.
I'm close friends with a cat breeder and she sells kittens at $300-500 and that's before deducting the care costs. That's 2 full months of socialization, training, vet checks, vaccinations, and care packages, as well as the fact that her one male cat needs a whole separate room for himself. I would say it's at least marginally easier and more profitable to breed one pair of ball pythons.
That being said, I'm in no way in it for the money myself. I love my snakes for what they are. I have one breeding plan that's 2 years in the making and I'd be more than happy if the money I got would cover their feeding costs.
