Look at the provided table image. Your goal is to find the locations of the specified cells. Remember to represent a cell's location using the JSON {'value': '<cell value>', 'location': (row number, column number)}. Both row and column number begin from 1. For the case where a cell is not contained in the table, its location should be denoted as 'DOES NOT EXIST'.

2. '4',
3. '11',
4. '1',
5. '20',
6. '14',
7. 'Frequency',
8. 'Number of pets',

The target cell locations are as follows:
1. {'value': '13', 'location': (6, 2)}
2. {'value': '4', 'location': (7, 1)}
3. {'value': '11', 'location': (3, 2)}
4. {'value': '1', 'location': (4, 1)}
5. {'value': '20', 'location': (8, 2)}
6. {'value': '14', 'location': (7, 2)}
