Yes. you can do by 

for i in grid:
    for j in i:
        if grid[i][j] == 'cat':
            print i, j

Output:

0 1

You could iterate over all the elements like this:

def find(needle, hay):
  for x in hay:
    for y in x:
      if hay[x][y] == needle: return x, y
  return -1, -1

And then use this function

find('cat', grid)
