Find index of an arbitrary cell array that contains a string

In This thread, @Jan answers the question in the title for the case of cell arrays that consist only of character variables.

It doesn't work for more cell arrays that contain numbers and variables, e.g.,

dog = {1,'cat'}
Index = find(contains(dog,'cat'))

returns an error. Could somebody explain the solution for the case of general arrays? Thanks

Index = find(strcmp(dog,'cat'))
