Lexus really needs to go see a vet as soon as possible. A long term nose bleed is a medical emergency. My main concerns would be exposure to toxin that might affect his ability to clot his blood. This could be rat poison or another toxin. However a foreign object up his nose, trauma and infection can cause bleeding too. He needs to have blood work to detect if he is clotting his blood and make sure his platelet number is normal. If he will let you apply pressure to his nose and maybe even ice to the bride of the nose to slow the bleeding until you get him into a vet.
