At least that is what my husband reacons happened when I took the kids to the Pet shop early in August and came home with two ratlets, cage and food things....
The rat in this image is Dave (she's a girl;-) Here she is about 5-6 weeks old.
After a some what stressy start (the 3 yr old would not leave them alone...) they have grown into a fine pair of young rats. Their cage and run area is constantly evolving as they become tamer and we think of new things to make for their amusement.
This exercise is in part a Home Ed project centered on Health and Physical Ed, with forays into Tech and Science.
But really I got them because I felt outnumbered and needed some female pets to even up the gender balance in the house;-)
