There shouldn't be a situation where you would want do something like
if($string =~ /cat/ && $string !~ /catapult/)

print 'String matches cat but not catapult';

since you could quite easily construct a single regular expression
which would suit your needs rather than testing a match and a
non-match.
Here's one way you could do it (as usual TIMTOWTDI) using capturing
parentheses (untested)
if($string =~ /cat(\S)/)
{
if($1 eq 'apult')
{
print 'It has a cat but I do not want catapult'
}
else
{
print "I do want $string";
}
}
else
{
print "Do not want $string as it does not contain cat";
}
.
