I dont think so. How I read it, it will go like this: Pygmy pythons according to Table A6 are a Cat A animal. According to Table 2 one Cat A animal after 18 months of age will require an area of 0.15m2. So of this area of 0.15m2, the shortest side cant be less than 20% of the total length of the biggest snake (Standard 188.8.131.52). If you keep more than 2 in the cage, you will have to add 50% to the 0.15m2, three snakes add 70% (Standard 184.108.40.206). So after the 18 months of age it goes into an adult cage size (Standard 220.127.116.11), to be honest I dont know why Appendix B was added to document, so far I cant see any references to it.
