He makes sure that the mice don't spoil the parcels.

Sameeee! Our cats are also our greatest mouse control here because ever since we adopted cats, not a mouse has been seen in our house.

They're really effective in doing so because I sometimes see them walking around our house with a mouse dangling in their mouth, and there's even one time where one of our cats brought a small dead snake! We were terrified when we saw him dragging it haha

Plus, our cats also became our stress reliever...I don't know but they seemed to notice when I'm stressed, and that's when they let me pet them for a longer period (⁠ ⁠ꈍ⁠ᴗ⁠ꈍ⁠)
