So my momma mouse that ate all her babies (except for one) was dead when I got home from work. I got the pup out of the cage and cleaned the cage out. Hes in a little plastic critter tote. I tried to put him in the tank with my other set of female that im letting mature, they instantly tried to kill him. I held him in my hand to comfort him after they tried to attack him and he moved his head accros my hand and left a faint trail of what seemed like bloody saliva. The mouse that was giving him crap only ipt him on the butt and he scattered away so Im 99% sure the blood isnt from that. When I got him out of his mommas tank I saw what seemedlike blood on his genital area aswell. Could this be some sickness or malnutrion from momma dying. What do I do with him?
