Question about Labor

[Janet Morrow]

I have a question.  Today is day 25 for Hanna.  this morning she is not following her regular schedule.  By this time of the morning she and Jo-Jo are usually sleeping.  Right now Hanna if madly digging at a corner of their tank.  (this is unusual for her.  She does some digging, but not like this.)  Jo-Jo is in the nest  ripping and shredding tissue.   Is this a normal sign of early labor?  She still is coming to see me everytime I look in.  And she did take the sunflower seeds that I offered her earlier this morning   Janet & Elizabeth Mountain Ash
