You should be able to put what you have as the temp table definition query
as a subselect in join probably. So something like the following:

SELECT c.*,r.* FROM cages c LEFT JOIN (SELECT * from reserved_cages r
WHERE r.date_in <= '2008-02-15' AND r.date_out >= '2008-02-15') r ON
(c.id=r.cage_id) WHERE (c.cages_type_id=1 AND c.id>0) ORDER BY
order_position;
