This analysis explores whether pet owners have better physical health outcomes, and if so, whether the positive physical health benefits are explained by better health behaviors that result from having to take care of the pet's physical needs. Data come from the National Health and Nutrition Examination Survey (NHANES), a representative sample of the non-institutionalized United States population. Analyses were limited to persons living alone (n=2474) in order to isolate primary pet caretakers from those merely living in a pet household. Results showed that pet owners, particularly dog and cat owners, had more positive physical health outcomes when compared to non pet owners or those owning other types of pets. Surprisingly, the effect of pet ownership was not mediated by health behaviors such as recreational walking. However, the health benefits of pet ownership were largely reduced once sociodemographic variables such as age, socioeconomic status, and residential location were controlled. The positive health effects of pet ownership appear to be primarily the result of selection, not increased physical activity associated with the active caretaking of pets.

Retinal projections were examined in two tyrosinase-negative albino cats using autoradiographic techniques. Cats from this colony have pink eyes; their retinal pigment epithelium, ciliary body, and iris epithelium are completely devoid of melanin pigment. Test breeding for five generations indicates that these cats are true albinos (cc). The most striking feature of the albino cats' visual pathways was a reduction in ipsilateral input which was more severe than that reported for Siamese cats. The only evidence of ipsilateral input to the laminated dorsal lateral geniculate nucleus of the albino was a small lateral normal segment and a small projection to the lateral portion of lamina C1. Ipsilateral projections to the medial interlaminar nucleus, retinal recipient zone of the pulvinar complex, ventral lateral geniculate nucleus, superior colliculus, and pretectum also were reduced. Ipsilateral projections to the suprachiasmatic nucleus appeared to be normal in the albino cats studied. Our findings indicate that, compared to the normal cat as well as to the tyrosine-positive Siamese cat, the tyrosinase-negative albino has reduced ipsilateral retinal projections. The albino cat is a model system analogous to tyrosinase-negative albinism found in mammals.

Southeastern Utah is a rugged and colorful portion of the state. As a part of the Colorado Plateau Physiographic Province it is characterized by an arid climate, multicolored but mostly red sandstones, shales and limestones, weathered sand deep box canyons, and high, isolated, lacolithic mountain ranges. Despite the general aridity of the region there are several major rivers and streams. The Green and Colorado rivers converge southwest of Moab. Main tributaries below this point are the Fremont, Escalante, and San Juan rivers. The latter drains extreme southeastern Utah.
