My Black Rat female is quite shy, even weeks after coming to her new home. (She has a 60-gallon vivarium with naturalistic setup, 6 times larger than her former setup.) I had hoped for more inquisitiveness & activity, but she tends to stay hidden well over 95% of the time in the same corner.
Once out of her "room", she handles like a gem, and I enjoy her demeanor. She never hisses, musks nor bites.
I hear from others that their Black Rats are quite active, constantly exploring their cages. I've also learned from experience that there may be a gender issue here. Males of many snake species tend to be quite active & inquisitive; females are less so.
Are your females prone to stay hidden in the same spot of their enclosure, or do you find that behavior greatly depends on the individual?
