One situation is pure love. Some people may like ornaments belonging to their own animals, or other animal ornaments, and buy them and put them on their desks.
In the second case, in order to put the objects in the room beautifully and harmoniously, put the appropriate animal sculptures in the right position in the room to make the whole room look patchwork.
The third situation may be the most, looking for someone to read it, or taking animal homophones and putting them on the table or in a specific position, giving them special meanings or hints, in order to work and live smoothly.
