Unlikely nursemaid:

Wallace and Ann have always been fond of animals. When they spotted a small kitten in their yard, its companion surprised them. They left food out for the kitten, but a crow had already taken on the responsibility as caretaker. The crow was already feeding and bringing the kitten water! The crow even served as the kitten's protector. Wallace and Ann named the kitten Cassie, and the crow Moses. They believe if Moses hadn't adopted Cassie, the kitten would never have survived. Wallace and Ann say we could all learn a lot from these unlikely friends.

The nose knows:

Although Ray and Carol were bedridden and recovering from surgery, they were suspicious of their headaches and sleepiness. During this time, their constant companion was their tabby cat, Ringo. One day, Ringo insisted on being let out, but he wouldn't go outside until Carol followed him. When she did, he led her to a spot in their landscaping and began digging. Carol immediately smelled gas. The gas company told Ray and Carol the leak was so strong that one small spark could have caused an explosion. Ringo went on to sniff out two more gas leaks in the neighborhood, and was given The Humane Society's Award for Bravery
