[0071] In a specific embodiment, the opening and closing door 31 is a double door, and the edges of the two doors close to the body of the scoop 1 are fixedly connected or rotatably connected with the edges of the downward opening of the body of the scoop 1. As shown in the drawings, the edges of the two doors close to the body of the scoop 1 are rotatably connected with the edges of the downward opening of the body of the scoop 1. Figures 1-4
[0072] In a specific embodiment, the scoop includes a weight sensor for obtaining the weight of the mice in the scoop.
[0073] After scooping the mice, the weight sensor senses the weight of the mice and outputs a signal, so that the operator can basically understand the number and approximate weight of the mice according to the output parameters, and master the basic physiological conditions of the mice.

[0075] In a specific embodiment, the body of the scoop 1 is a silica gel scoop body or a plastic scoop body, thereby reducing noise during scooping to minimize the risk of stress to the mice while facilitating cleaning.
[0076] By using a silent material and setting a non-slip pad, it is ensured that sharp noise occurs during the scooping of the mice, so that the mice are startled and stimulated, and the setting of the non-slip pad further ensures the softness and non-slip of the mice on the opening and closing door 31, improves the comfort of the scoop, and avoids stress or injury to the mice.
[0077] As shown in the drawings, in an embodiment, the surface of the hand-held part 2 is provided with a non-slip texture 21. This allows the operator to be more comfortable and avoid hand slipping when changing bedding and scooping mice, making the operation more convenient. Figures 1-4
