Hi everyone, I am new to the forum and I'm not even sure if this is the place to post this but I was hoping you could help me. A friend of mine needed to rehome their bunny and I adopted him. He's been with me for three days now but still hasn't left his cage. He lets me pet him and seems happy (has been eating normally and playing inside his cage) but he doesn't come out to explore the house. I already bunny proofed everything so it's safe for him. Do you think he might be sad for living his previous owner? Is there anything I can do to encourage him to leave the cage? Thanks for your help!
