kitty is a tall and slim entity. he is entirely black. he is very friendly, until you stay in his level for 200/201 days. if you do so, he will kick you out the level back to where you noclipped from (in your case, being level 0). kitty will teleport to the wanderers position when they move. kitty cannot talk due to being faceless, so he communicates through writings on the walls. there is also wifi in his level, so if you had any devices like phones or computers with you, you can use them here.
