Why are my cat's eyes uneven after dental anesthesia?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | neutered | 12 years and 2 months old | 12 lbs

My cat just had his teeth cleaned. One eye is still dilated and the other is lazy. Is this normal after anesthesia?

By your description, it sounds as though Orion may have developed Horner's syndrome or other neurologic deficit, or is having an abnormal reaction to his anesthesia or pain medications. This is not typically a normal post-anesthetic finding, but I just read a few rare reports of cats developing Horner's syndrome after anesthetized dental cleanings. Call your vet to discuss Orion's clinical signs so that he can have a full neurologic exam performed.
