Small white rat with a brown spot over the head sitting inside an open cage

Math was adopted Sept 18 2022 with his two "brothers" Science and Math. He was a rascal and the most adventurous of the three and never let an enclosure keep him in. I would always find him outside whatever area I had designated as theirs; trying to explore every nook and cranny of my apartment. He was a very cuddly rat and loved to lay in my hoodie pockets and nap the days away. He has now joined his brothers who have passed before him, and the three are together once more.
