Why not use: cat $FILE |gzip >$FILE.gz

Because gzip has a "-c --stdout --to-stdout" option. 

    gzip -c "$FILE" > "$FILE.gz" 



If you want to "cat" several members:

<quote source="man gzip">
In  case of damage to one member of a .gz file, other members can still
be recovered (if the damaged member is removed). However, you  can  get
better compression by compressing all members at once:
    cat file1 file2 | gzip > foo.gz
compresses better than
    gzip -c file1 file2 > foo.gz
