Ursula, a 5-year-old female cat, is the Red Desert Humane Society Pet of the Week. She is very sweet but is a bit nervous until she gets to know people, staff said. Ursula is spayed, current on vaccinations and litter-box trained. To see her, visit the Red Desert Humane Society, 310 Yellowstone Road, Rock Springs. It is open noon to 6 p.m. Tuesday through Saturday.
