I read the post about roachback. I feel my Sadie Mae may have this. I searched the internet for information and cannot find any. Could somebody here please help me? I am a little concerned about this. Sadie is 2 1/2 yrs old and I really didn't notice this(I didn't really know what was) until I got my new furbaby. Lillie has a very straight back where as Sadie doesn't. Is this something I need to be concerned about? She runs,jumps, plays just fine. Should I try to stop her from jumping?

Thank you in advance for any help you can offer me.
