Modular fence assembly

A modular fence assembly, comprising:

• multiple fence modules each comprising:
• a barrier comprising a pair of substantially parallel end posts, and
• a base comprising a moderately-sloped, substantially planar, hollow platform extending downwardly from a first side of said barrier, wherein said platform:
• comprises one or more lower edges configured to engage the surface on which said fence module is positioned,
• is disposed substantially orthogonally to said barrier, and
• extends from the first side of said barrier to a length equal to between 25% and 100% of a height of said barrier,
• thereby said platform is configured to stabilize the respective fence module on a surface and allow an animal or a human to stand, sit, or crawl on said platform, such that, if the animal or human push or lean with force against said barrier while dwelling on said platform, the body weight of the animal or human counteracts the pushing or leaning force and does not allow the fence module to topple over;
• and
• multiple connectors each configured to connect two adjacent fence modules of said multiple fence modules, wherein each of said multiple connectors is configured as a double hinge having a pair of parallel internal channels that are each configured to embrace an end post of one of the two adjacent fence modules;
• wherein said multiple fence modules and said multiple connectors are configured to be assembled into a fence, and
• wherein said bases of said multiple fence modules are configured to fit underneath one another when said multiple fence modules are stacked in parallel, with the lower edges of said platforms of said multiple fence modules engaging the surface.
