You can tell a baby mouse is a mouse by looking at its size, shape, and features. Newborn mice are tiny, hairless, and pink, with closed eyes and big round ears that lie flat at first. As they grow, they develop soft fur, their eyes open at about 2 weeks old, and their tails become long and thin — about the same length as their body. Baby mice are also much smaller than baby rats; they have smaller heads, more delicate features, and shorter feet. If the tail is long, the ears are large goto.now/YJkWW👈🏻
