Alexis Gerbil Runs in the Ball

Music by Kevin MacLeod Incompetech.com "Rock On Chicago" There are different opinions whether balls are good for gerbils. I see some discussions get pretty heated about this topic. I think what some people say about the balls make a lot of sense, where backs can get hurt, etc. I also believe pet owners should make their decisions to what they think is best after learning the facts. Are there real facts out there? I do not know. I also believe some people should be left alone to enjoy their animals. We have them because we love them and want them to be happy.
