Mikki has LP and my vet did say it was genetics.  She has a high grade and is still ok.  We do have stairs for her to go up and down on the bed.  And we pick her up instead of letting her jump.  Other than that, he has not recommended surgery or anything at this point.  If I remember correctly, it is a grade on a scale of 1 to 5.  Mikki has a 4.
