Known as a cat fanatic, he often shares pictures of his pets on his personal Instagram account. He also created the logo for his solo activities around a drawing of a cat. The back of the photocards not only boast the logo, but a caption of what the cat is thinking in the shot and an illustration of a box, known to be a cat's favorite thing to jump into.

Netizens reacted positively to the idol's devotion to his pets, with some even adding that he somewhat resembles them.

"He has three cats?" one netizen asked. "So adorable. The thought to put these photocards inside is adorable too."

Another netizen reacted to just how much fans knew about the singer's cats, commenting, "Fans who like a singer all the way to being fans of their pets are so cute," and adding Sehun of EXO's Vivi, V of BTS's Yeontan, and Taeyeon's Zero as other examples of popular celebrity pets.
