Why my have Cat watery right eye?

just take it 2 the vet or blow in it

Do NOT blow on it. It couldbe a foreign body which may cause corneal damage. If you must treat it at home, use a steriile eye-wash from the Pet store or drug store. People brand is OK, but eyewash, NOT wetting solution of anything for contacts.Some forms of conjunctivitis are transmissible to other pets. Take it to the Vet if at all possible, and if you have a protective cone like the Vet uses on cats after surgery, use it to prevent cat from rubbing the eye .
