I miss my little male mouse. I kept him alone in a 10 gallon and he was so sweet. He would fall asleep in my hand from me rubbing my finger on his cheek. I say def get the mouse. He was a long haired field mouse? Not sure. He was so sweet and he was a tan/grey color.
Ha! my mom had an albino rat in a ferret cage the spoiled baby. He was interesting too. He was a baby of a pair I bred and I swear he was part dog. He would lick your face like one anyways.
