Its time for a Silhouette update! Thank you for the advice, it really helped, and we are making slow progress! Laceris occasionally comes out, though only during dark hours, and sometimes, I can see him! Like you said, I kept in him a room, where he immediately jumped in a drawer, where he still stays as his "safe spot". I keep a bowl of cat food outside to encourage him. Soon I'm sure he'll be more friendly! Again, thanks for the advice!
Press space! :D Silhouettes, and this design by @Silenq_Riverz All art by me!
