Depends on what kind of dog or cat you have, I choose dogs because at my moms place they got a purebred black labador and that dog is elite very obediant is loves to go hunting. Then at where I live right now we got a purebred chocolate labador which is still kinda young and learning but shes smart and fun to play with and plus if you dont want her around just say 'outside' and point and she goes away =P
