I'm giving this two stars by subtracting a star for each of three things:
1) She writes in a condescending tone to you throughout the book.
2) Inconsistencies -p. 79 says labs need to be fed twicea day after 8 weeks. Then it says 4 times a day between 2 and 4 months old. Poorly reviewed.
3) Not practical - at one point the author suggests to reduce or quit your job, and if you work, spend 2 hours from 530 to 730am solely doing lab activities. And that's just part of your day, every day.
