What Causes Cats to Sneeze Blood?
There are multiple reasons a cat may be sneezing blood, some being more severe than others.

When the cat experiences chronic sneezing or nosebleeds and does not eat, it is necessary to contact a veterinarian as soon as possible.

What to Do If Your Cat Is Sneezing Blood
If your cat is sneezing blood, you’ll need to act quickly and contact the veterinarian as soon as possible. Before going to the vet, try to stop the bleeding if it is severe. You can do this by applying a cold compress or ice pack to the bridge of your cat's nose. If your cat won’t stand still or is struggling, skip this step, and take them to the vet immediately. Keeping your cat calm will help slow or stop the bleeding. You can do this by moving your pet to a quiet and comfortable environment, where there are no stressors.
You should not try to treat the condition yourself at home or administer any kind of medicine without talking to the veterinarian first. Depending on the cause of the blood sneezing, the vet will institute the appropriate treatment (antibiotics, antifungals, foreign body extraction, etc.).
If your cat sneezes frequently but there’s no blood and they otherwise behave normally.
Here's what you can do:

Diagnosing and Treating a Cat That Is Sneezing Blood
To diagnose your pet, the vet will ask several questions about your cat's medical history and other factors that may help establish a correct diagnosis, such as whether your cat has ingested rat poison or human medications.
