Question : SQL 2005 SELECT Statement "NOT CONTAINS 'cat'"

Here's the SQL statement I'm trying to execute!
SELECT       DISTINCT merchantCategory
FROM            dbo.Items
WHERE NOT CONTAINS 'cat'
In other words, I want it to cough up all the unique results for merchantCategory that don't contain the keyword 'cat'. I know the syntax is wrong somewhere around 'cat'; I'm just not sure what it is. Please help, Thanks, Chris.

Answer : SQL 2005 SELECT Statement "NOT CONTAINS 'cat'"

FROM     dbo.Items
 WHERE merchantCategory NOT LIKE '%cat%'
