in thread need help in editing multiple word in a file

consider this example: lion is brave animal. cat is brave animal. dog is brave animal. in this i want to change brave by frightened only for cat. so i need to match cat and replace brave with frightened. So match file is like: cat frightened . Thanks.

Ok, so how do you propose deciding which word in the string:

cat is brave animal

should be replaced by 'frightened'?

In other words, is this also acceptable:

cat frightened brave animal

?
