Do monitors only grow to the size of their enclosures?
No, this is a myth. Monitors will continue to grow regardless of cage size and in too small of a cage this can cause serious health problems. The monitor will not be able to thermoregulate and can easily overheat. There have been cases where monitors spines have become crooked from growing in a cage that was too small. Besides being cruel, a monitor will more than likely die if kept in a cage which is too small. The cage should be large enough to allow for plenty of choices in movement and hiding areas.
