Claim 1:
2. The animal containment system of claim 1, further comprising:
a second animal containment structure, comprising:
a second front wall having a transparent portion; and
a second light-polarization system removably attached to the second front wall and covering the transparent portion, the second light-polarization system comprising:
a second retaining member having a sidewall with a length and having one or more interior channels along the length; and
a third polarizing panel removably engaged with the one or more interior channels of the second retaining member, the third polarizing panel comprising a third light filter having a third polarization axis; and

a third animal containment structure, comprising:
a third front wall having a transparent portion positioned such that a viewpoint through the transparent portion of the third front wall includes at least a portion of the second front wall of the second animal containment structure; and
a third light-polarization system removably attached to the third front wall and covering the transparent portion, the third light-polarization system comprising:
a third retaining member having a sidewall with a length and having one or more interior channels along the length; and
a fourth polarizing panel engaged with the one or more interior channels of the third retaining member, the fourth polarizing panel comprising a fourth light filter having a fourth polarization axis that is orthogonal to the third polarization axis of the second light filter of the second light-polarization system of the second animal containment structure.
