I would have to say the kill shelter. b/c the ones there, like others have been saying, get killed everyday for no reason at all, exsept for that there is no one out there that has said "I'll take that dog home with me today!" or what ever kind of animal it was. I have never adopted a pet from a kill shelter, or any kind of shelter. I have always gotten my animals from people who worked with my mom. I dont know what its like to adopt from a shelter. I may never know. I did try to adopt a cat there but it didnt work out with Snowball.
