Claim 19:
20. An animal containment system light-polarization system kit, comprising:
a 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, the first retaining member having a first side portion, a second side portion laterally opposed from the first side portion, and a bottom portion extending between the first side portion and the second side portion; the first side portion, the second side portion, and the bottom portion cooperating to create a receiving space having an opening opposite the bottom portion;
a first polarizing panel removably engageable with a first one of the laterally adjacent interior channels through the receiving space of the first retaining member, the first polarizing panel comprising a first light filter having a first polarization axis such that the first light filter blocks a first half of wavelengths of visible light waves; and
a second polarizing panel removably engageable with a second one of the laterally adjacent interior channels through the receiving space 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 second light filter blocks a second half of wavelengths of visible light waves; and

a second light-polarization system, comprising:
a second retaining member having a sidewall with a length and having two laterally adjacent interior channels along the length, the second retaining member having a first side portion, a second side portion laterally opposed from the first side portion, and a bottom portion extending between the first side portion and the second side portion; the first side portion, the second side portion, and the bottom portion cooperating to create a receiving space having an opening opposite the bottom portion;
a third polarizing panel removably engageable with a first one of the laterally adjacent interior channels through the receiving space of the second retaining member, the third polarizing panel comprising a third light filter having a third polarization axis such that the third light filter blocks a first half of wavelengths of visible light waves; and
a fourth polarizing panel removably engageable with a second one of the laterally adjacent interior channels through the receiving space of the second 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 third light filter of the third polarizing panel, such that the fourth light filter blocks a second half of wavelengths of visible light waves.
