Stickers was totally freaked out by humans when I first got her (she was a pet store bought bun for a child with I believe autism, so no wonder, kept in a tiny tiny cage), but the key to calming her was to just sit in the room with her and ignore her. When she came to explore, I didn’t move and let her sniff / walk on me all she wanted. When I walked in the room for anything, I would say in a calm, nice voice good morning or something of the like and after she was comfortable enough with me, I would offer a treat when I came in (break up 1 baby carrot into a bunch of pieces and give one piece whenever I walked into the room). Eventually she started running up to greet me expecting her treat and as she let me pet her, I started swapping treat for pets.
Now she is comfortable enough with humans, but she’s still skittish – it’s just her nature. If I surprise her in any way she bolts like a predator is after her. Once she realizes it’s me, she’ll thump in displeasure of her slave being mean enough to scare her. lol Which is a big turn from when I first got her, she laid down belly flat on the ground and peed on herself out of fear when I got too close.
Obviously you can’t use treats til the bun is old enough if he’s under 12 weeks though*
He’s a cutie and good luck with him!
