why can't insert my code to mysql? INSERT INTO

INSERT INTO cats(name, breed, age) 
VALUES ('Ringo', 'Tabby', 4),
       ('Cindy', 'Maine Coon', 10),
       ('Dumbledore', 'Maine Coon', 11),
       ('Egg', 'Persian', 4),
       ('Misty', 'Tabby', 13),
       ('George Michael', 'Ragdoll', 9),
       ('Jackson', 'Sphynx', 7);

those ones can insert but

INSERT INTO cats (name, breed, age) 
VALUES  ('Ringo', 'Tabby' 4), 
('Cindy', 'Maine Coon', 10), 
('Dumbledore','Maine Coon',11), 
('Egg', 'Persian', 4), 
('Misty', 'Tabby',13), 
('George Michael', 'Ragdoll', 9),
('Jackson', 'Sphynx’ ,7);
