This is a mouse and not rat, right? It looks too small for a rat. Frankly, I don't know how to differentiate them other than their size and that a rat looks...nastier? *shrug* This mouse was found in the room I slept in at my sister's place. I guessed that it managed to squeezed between the window panels and the insect screen panels. For your information, at that time, I pushed the different panels to different sides. I agreed with my brother-in-law that it looked quite cute but naturally we couldn't have a mouse running around the house, especially with a toddler and a dog in the house It eventually left the room through the window after my bro-in-law pushed the insect screen panels to the right, where the window panels were. From then on, we have to make sure panels are shut.
