I understand completely.  I was worried about Trixie when she porked up and got sort of lazy after her first litter.  I just put her on a lower fat food and threw that rope a few extra times.  I wasn't worried about her weight so much as I was concerned if it was unhealthy.  Come tomorrow she'll have someone there to give her a nice little work out.
 
  
How excited are you, BTW?
