    The root cap slime or mucilage has generally been
    considered to provide lubrication and protection to the root
    as it grows through the soil (e.g. Fritsch and Salisbury,
    1938; Juniper and Pask, 1973), although recent work by
    Guinel and McCully (1986) stresses that this view may have
    limited applicability. A variation on this theme was
    suggested by Esau (1953) who proposed that the mucilage
    might aid separation between the root cap and sloughing
    cells. However, in view of the prominence of root caps in
    hydrophytes, she further suggested that here the cap might
    perform other functions. The aerial roots of Cattleya were
    studied by Mollenhauer (1967) who suggested that the root
    cap slime might act as a water-absorbing material since a
    lubricant ro#le was considered unlikely here. Additional
    involvement in influencing the availability of soil-borne
    chemical elements has also been suggested for root exudates,
    such as mucilage (e.g. Jauregui and Reisenauer, 1982;
    Mench, Morel and Guckert, 1987), and in interactions
    between micro-organisms and the root surface (reviewed by
    Rougier and Chaboud, 1985). The mucilage is also believed
    to have a ro#le in gravitropism (e.g. Miller and Moore, 1990).
    By analogy with the principal function proposed for the
    root cap, it has been suggested that the ligule secretory
    produce might act as a ‘lubricant’ which eases the exsertion
    of the enclosed leaf or culm (Chaffey, 1983, 1994).maybe this is the answer

    So, in other words, its normal for Catts? They just aren't sure why they do this.

    you wouldnt guess today the slime has completely gone how weird maybe it has to do with the high humidity we were having which had settled the last couple of days but the rain is back and the humidity is up again we shall see what happens this time
