cat to a file but retain header

Hi,
Is there a way to write to a txt file each day but retain the header on the file? I'm cat'ing 5 files into one .txt file each day but I want the new data to be written after the first 2 lines which are:

Code:
Progname  Size  Date  Owner
----------------------------

Basically I want my new files to be merged into the one but starting at line 3..

Any help much appreciated as usual!
