I have not read or seen any references as to how African rats mark their territory, but the behavior I have witnessed is that females sometimes drag their rear end, urine marking as they walk; and males rub their cheeks on
walls, etc.,
in a
similar manner to cats.
Neil and his Scottish friends had quite a laugh at the Unity Homes party; no doubt the laugh is on all of us here
in North America who are just beginning to look at sustainable design
in such a disciplined and thorough
manner, who are just starting to do green prefabricated
walls like this, (more to come on Unity Homes themselves, who use
similar technology) and where architects rarely become design - builders of this scale and sophistication.
