My Cat Is Drooling, Acting Drowsy, And Not Eating Or Drinking. I Just Noticed About Five Minutes Ago And I Am Panicking. It Is Almost 3 A.m. What Do I Do!?!

Excessive drooling in cats should be investigated by the vet because it can be due to many reasons. Common causes of this condition are

1. Foreign material in mouth
2. Gum and teeth diseases
3. Mouth ulcers
4. Ingestion of small lizard
5. Ingestion of medicines
6. Feline herpes
7. Liver disorders
8. Infection of salivary gland

Treatment depends upon underlying cause, so, take your cat to vet.
