Training him to walk on a leash since kittenhood has allowed this otherwise "indoor cat" to get some outdoor exercise with less chance of being hit by a car. I live next to a busy street; he'd probably be dead in 5 minutes if I allowed him to roam unsupervised. Neighbors may also appreciate not having another cat digging in their garden, killing birds, fighting with their cat, etc. www.hsus.org ... cats tricks leash harness clicker training behaviorism animal behavior pets ...
