Okay just a quick run down! As already touched on:
- Low maintenance (I'd like to stress, this is really great for people like myself with disablilties. I advocate snakes as the ultiate spoonies pet because of how little time, and physical and mental effort you have to dedicate to keep them happy, and they won't demand time and attention if you don't have it to give).
- Hypoallergenic
Add to that:
- Fascinating and unique
- Just plain beautiful
- Very inexpensive to set up, feed, and maintain (you don't have to get your snake yearly vaccinations, spayed or neutered, etc).
- Often gets bystanders/non-hobbyists interested in conservation and science when they meet a snake and make a connection (I do this with kids all the time) in a way normal domestic mammal pets do not
- There is scientific evidence that watching a snake slither has the same soothing effect as watching fish in an aquarium. (There's a name for the effect but I can't recall it and my google fu is being unhelpful atm).
- Something that might be specific to only a small subset of people, but having a snake slither over your hands is an amazing stim; again important for people who might need that sort of thing.
- and the most important imo is that, it brings you joy and satisfaction as a pet owner. That's all you really need tbh.
