Bleeding from the mouth in a cat can be caused by many things, some serious and some less so. Here are a few examples:
* Dental problems: Gum disease, broken teeth, or infected tooth roots.
* Trauma: A hit by a car, a fall, or a fight with another animal.
* Poisoning: Ingestion of toxic substances can cause internal bleeding.
* Upper respiratory infections: Inflammation of the nasal passages or throat.
* Cancer: Tumors in the mouth or throat.
* Coagulation disorders: Conditions that affect the blood's ability to clot.
What you should do:
1. Seek immediate veterinary attention. A veterinarian can examine your cat, determine the cause of the bleeding, and provide the necessary treatment.
2. Describe the bleeding to your vet. Tell them how long it has been going on, the color of the blood, how much blood is being lost, and whether your cat seems to be in pain.
3. Keep your cat calm and comfortable. Avoid touching the mouth area.
4. Follow your vet's instructions carefully.
