Would there be any reason for having this in the Code of Practice?????? I especially find the last sentence strange.
4.3.1.5 An enclosure housing two snakes must be at least 50% larger than the minimum enclosure size (see 5.3.1.2, 5.3.1.3 and Table 2). The enclosure size must be increased by at least 20% for each additional snake above two (e.g. an enclosure housing three snakes must be at least 70% larger than the minimum enclosure size). If different species are housed together, the calculation must be based on the minimum enclosure size for the largest species.
