I have to agree with Blue eyes here. I looked at your Patreon page and while I can understand your circumstances, I don't think that you will earn any money doing that kind of thing - you can find entire forums and websites about animal care for free. Moreover, and I'm not saying this to be mean, but having pets doesn't make you qualified to give advice about owning them correctly. Most people in here have spent years gathering informations by reading specialized articles, vet thesis and well-informed websites like the House rabbit society's, medirabbit..., or exchanging on forums with breeders and experienced owners. I've personally spent the last 10 years reading up everything I could find in French and English about the subject as well as raising rabbits. I'm not saying that you can't have anything of value to add because you are 15 years old, but I'm saying be careful about what you are writing about because if what you write is ill-advised you could end up hurting someone's pet - for example someone who would read your article, think there is no need to give his rabbit hay and end up with a rabbit dying of blockage or having severe teeth issues.
You say you've got seven rabbits - take this opportunity to learn more about them by reading up this forum and the House rabbit society's website. For example, a rabbit needs at least 5 hours out of his cage. Everyday.
About the money thing, it's not your responsability. I've been there. You're the kid, you have to concentrate on your studies so you can do well in the future and help your parents as an adult when the time comes. In the meanwhile, maybe you can babysit or find a job as a home tutor or something, those will be a lot more reliable than trying to earn money on the Internet.
