I'm so sorry. The blood from the mouth is a symptom of what your kitten died from, not the cause. There is no way to know for sure without a post-mortem exam. It could have been trauma or an infectious disease causing bleeding in the lungs.

    I'm so sorry Harold died today! He could have suffering head trauma causing the bleeding from the mouth and leading him to pass away. He could have also gotten into something toxic. Without seeing him in person, I can't say for certain what caused him to pass away but you can take him into the vet to get a necropsy (an autopsy for animals) to get some answers. Again, I'm so sorry for your loss :-(
