Top 20 cities at risk for rodent problems

San Antonio has moved up from No. 14 in the last survey. The fifth fastest-growing city (2007-08) has continued to reduce spending in most infrastructure maintenance categories. The bright side: With a population of just over 2 million, San Antonio has many other animal attractions so residents and tourists alike can enjoy the exotic animals from around the world at the Natural Bridge Wildlife Ranch or some not-so-exotic animals like bunnies, donkeys, ducks, turkeys, guinea pigs and worms at the Fiesta Farm.
