My leopard gecko artimes had blood coming from his vent 2 days ago. My parents won’t take him to a vet unless it happens again. What should I do?!

I am sorry that this is happening to Artimes. There are many places that blood could be coming from when it is seen around the vent. These areas include the gastrointestinal system, the reproductive system, and the urinary system. One thing you can try at home is to soak Artimes in lukewarm, chin deep water. This may make him defecate and/or urinate (poop and pee) and you can evaluate the material for additional blood. Please watch him closely while he is in the bath to ensure that he is able to hold his head up and there is no risk of him drowning. You can keep him in the bath for 15-20 minutes, and can do this once daily. In his cage, please replace his bedding with paper towels or newspaper, as this will allow you to see the blood easier and will keep him clean. If you do see blood again, I think your instincts were correct - I would recommend having him evaluated by a veterinarian. They can help to determine what system the blood is coming from. Please also monitor Artimes' appetite - if this decreases, I would also recommend taking him into a vet sooner rather than later. I hope this gives you a place to start!
