Is the Catechism of the Catholic Church considered scripture? Is the Catechism of the Catholic Church considered scripture? Does it have the same authority as the Bible? If not, what is its place in the church? Is it considered heresy to preach or believe something that is in contradiction with the Catechism?
The immediate answer is “No, it is not scripture.” Scripture is scripture and adding to it or subtracting from it is a no-no.
As to “Does it have the same authority as the Bible?” Well, I suppose the answer is “authority for what?” For some things the authority of the Catechism is superior (certain areas of theology are only hinted at in the Bible). It can be safely said, though, that there is nothing in the Catechism which contradicts the Bible (if the Catechism is taken as a whole and in light of a Catholic understanding of Scripture).
Can you contradict the Catechism without being called a heretic? That depends on how you contradict the Catechism. On certain matters it is more definitive than others and on some matters it is 100% correct. On other matters it is a bit more theologically ambiguous. It is important to remember:

This catechism aims at presenting an organic synthesis of the essential and fundamental contents of Catholic doctrine, as regards both faith and morals, in the light of the Second Vatican Council and the whole of the Church’s Tradition. Its principal sources are the Sacred Scriptures, the Fathers of the Church, the liturgy, and the Church’s Magisterium. It is intended to serve “as a point of reference for the catechisms or compendia that are composed in the various countries”. (CCC 11)

That word aims is important, because it is not a perfect synthesis and there are many, many finer points which can be debated and there is quite a bit of room for disagreement (you are talking about a Church which has a 1400 year old debate with its neighbor over one word). And it even testifies the the fact that it has not gotten everything perfect for all times and all people:

By design, this Catechism does not set out to provide the adaptation of doctrinal presentations and catechetical methods required by the differences of culture, age, spiritual maturity, and social and ecclesial condition among all those to whom it is addressed. Such indispensable adaptations are the responsibility of particular catechisms and, even more, of those who instruct the faithful:

Whoever teaches must become “all things to all men” (⇒ I Cor 9:22), to win everyone to Christ. . . Above all, teachers must not imagine that a single kind of soul has been entrusted to them, and that consequently it is lawful to teach and form equally all the faithful in true piety with one and the same method! Let them realize that some are in Christ as newborn babes, others as adolescents, and still others as adults in full command of their powers.... Those who are called to the ministry of preaching must suit their words to the maturity and understanding of their hearers, as they hand on the teaching of the mysteries of faith and the rules of moral conduct. (CCC 24)


All of that said, it is very difficult to contradict the Catechism without contradicting some important and definitive doctrine.
I know of one place, for example, which is phrased very poorly (in an attempt to guide pastors to a more compassionate action). My disagreement is perfectly acceptable and reasonable (as I agree with the teaching but not the admonition which goes along with it). On the other hand, if I were to disagree with the teaching behind the phraseological error I actually would be contradicting some very authoritative doctrines in the Church. That would be, at a minimum, a form of heresy.
