This solusion is not good because of the _AND_.   You say:
the subject contains "cat"  _AND_ not "dogs"  but the question ask for
"cat" and "dog"   _OR_    "cat"  only!

Try this:

*  2^0  ^Subject: .*\<cat\>
* -1^0  ^Subject: .*\<dogs*\>

If "cat",  score=3D2 (true)
If "dog",  score=3D-1 (false)
if "cat" and "dog",  score=3D1 (true)
if "caterpiler", score=3D0 (false)
