Not really sure, it would be close but I think it might be a little tight. I've got a pair of young macklotts and while they're longer, they're also more slender. However they're also fairly active. I'd feel better with a 4 foot cage for adult macklotts. Savu pythons on the other hand would probably be good. Another one that might be good would be irian jaya carpets, Morelia spilota variegata, which stay smaller then the other carpets.
