It depends on the breed. Many of the "newer" breeds (ragdolls, rag-amuffins), and many of the larger breeds do not reach maturity till they are 2 or three. Of course, that doesn't mean they won't go into heat or start to tom, so do fix them. :-)
most "cat cats" are about 12 -18 months for full size and maturity.

My friend Maggie's mom said that Maine Coon kitties keep growing in one way or the other (like filling out and bulking up) until they are 3 or 4. Wow! That means I have two and a half more years until I'm full grown!
