Less traditional four-legged animals such as ferrets, mice, rats, gerbils, hamsters, and guinea pigs have also found callings as therapy animals in recent years. Rats have proven to be especially suitable because their extremely high intelligence makes them particularly intuitive to human emotions, as well as being much more affectionate creatures than other rodent species like mice. While rats are often given a bad name (indeed, they are frequently considered to be vermin), they actually form close relationships with us. At the Children's Therapy Center of Washington Hospital in Peters Township, Washington, Pennsylvania, rats provide therapy for children with autism. The center's facilitator, Ms. Pollock, admits to having had a number of reservations about the use of rats in this context. However, upon seeing the interactions between these animals and the children, her eyes were opened to the difference rat-assisted therapy could make to these children's lives. It's not just children that can be affected by these animals, though. Some university students have recently benefited from interactions with these creatures. At Park University in Parkville, Missouri, pet therapy sessions were organized with MO KAN Pet Partners in the campus library for students undertaking their finals in order to reduce stress levels. While dogs, cats and horses were all involved there was also, due to their highly sociable nature, a rat. One of the instructors, Julie Goodman, commented that "Park University, like other universities, has realized the power of the healing touch of animals."
