Good Morning Amy and welcome! I am Dr. Loretta, a licensed veterinarian and I am happy to answer your question.
Most likely Douglas has a Urinary Tract Infection (UTI), Amy. These signs of many trips to the litter box with little coming out and blood in the urine are very typical for this. This infection in females and males makes them feel like they have to go all the time even if they have no urine in their bladder. This will require antibiotics. For now, go to the pet store and purchase a product called Methigel. Give Douglas a dose of this on his nose every 4 hrs. This is a urinary acidifier that causes the urine to be in an acid state so the bacteria cannot grow. This will not cure this but will prevent further bacterial growth until you can get Douglas to your vet.
Does that make sense to you, Amy?
Please let me know if you have ANY other questions. My goal is to give you 100% satisfaction and if you are not yet satisfied, please REPLY so I can clarify for you.
