Answer 1

You need use regex from here :

df['count'] = df.temp.str.count(r'(?<!\S)Male-Cat(?!\S)')
print (df)

                                           temp  count
0  Male-Cat Female-Cat Male-Cat-Female Male-Cat      2
1                               Male-Cat-Female      0
2                                      Male-Cat      1
3             Male-Cat Male-Cat Male-Cat-Female      2
4                    Male-Cat Male-Cat Male-Cat      3
