Claim 0:
1. An animal containment system, comprising:
a first animal containment structure, comprising:
a first front wall having a transparent portion positioned such that a viewpoint through the transparent portion of the first front wall includes at least a portion of a second front wall of a second animal containment structure; and
a first light-polarization system removably attached to the first front wall and covering the transparent portion, the first light-polarization system comprising:
a first retaining member having a sidewall with a length and having two laterally adjacent interior channels along the length;
a first polarizing panel removably engaged with a first one of the laterally adjacent interior channels of the first retaining member, the first polarizing panel comprising a first light filter having a first polarization axis; and
a second polarizing panel removably engaged with a second one of the laterally adjacent interior channels of the first retaining member, the second polarizing panel comprising a second light filter having a second polarization axis that is orthogonal to the first polarization axis of the first light filter of the first polarizing panel, such that the first light-polarization system blocks visible light waves from entering and leaving the first animal containment structure.
