Lizard Shedding

Shedding is the normal process of skin renewal.

Most lizards change colour prior to shedding; their overall shade gets progressively dimmer and duller around the head and limbs and grey/ white patches of skin begin to appear, progressing from head to tail. The shedding occurs on all parts of the body, including eyelids.

Behaviour

Lizards tend to rub themselves on surfaces to loosen the dead skin. Their behaviour may become more aggressive, especially while being held or touched.

While reptiles may still eat when in the very early phase of the pre-shed period, they usually lose their appetite as the period progresses, greatly reducing their food intake or even refrain from eating alltogether.

Possible Complications

To fasten the shed, it might be useful to bathe or spray the iguana with water. Indeed, in the wild, humidity in the air helps keep the old skin supple and therefore easier to peel off.

A healthy iguana will shed every 4-6 weeks during 1-2 weeks but young iguanas (2 to 3 years) may shed more often. Occasionally, a new shed may start before the previous one has ended. Shedding will slow down or stop during colder weather and decreased food intake. The absence of shedding which cannot be linked to seasonality may be an indicatior of an underlying problem, possibly associated with an inadequate diet, disease, stress, bacterial infections, parasite infestations, or other medical condition.

If the dead skin isn't shed, it may constrict the growth of the living tissue and result in tissue necrosis.
