I'm putting this in health because I don't intend on breeding and I am skeptical as to if I even have a pregnant mouse and because it is also a question on food and eating habits.
So my now 4 girls are going through about 8 tablespoons of their mix every day, is that too much? They have the tropical carnival mix for hamsters and I remove the peanuts and corn and set the sunflower seeds aside for use as treats. They eat everything in the mix and only leave shells. They are also getting meal worms twice a week and fresh veggies or fruit 3 times a week.
The concern about pregnancy could also just be putting on weight from eating/ potentially being in a larger home without the stress of the pet shop life could be allowing them to thicken up a bit. However Harley does look like she might be thickening quickly enough to cause me to pause and ponder. I have spent a lot of time observing them and checking gender and I'm fairly sure all of them are female but I have doubts about the larger black one, I can never get a good view of the underside to see more clearly. Does anyone have advice on how to get pictures so I can post and have you guys maybe take a shot at gender matching?
