He's still a boy this morning. So can (relatively) safely say that he is a he, haha. I think the problem was I wasn't doing it hard enough, so his bit didn't protrude enough, making it LOOK like a slit. I did it a bit harder and pop, boy part definitely. *whew*
And yes I imagine that he will be pretty upset to read the comments about him looking feminine... But he really does! LOL
He's settling in nicely! He's an explorer, this one. He likes the dogs as well. I had him hopping around the kitchen this morning and he was just happy as could be. He even came and sat in my lap for a bit, letting me pet him. He also did his first flop that I've seen... Right by Cooper, haha. He's not afraid any more! I have him set up in my room in a dog crate until I can bunny proof the kitchen a bit better and make a lowish babygate type thing so he can't get into the dining room.
Meanwhile Mary Jane can tell, and she's been sulking. I told her, "Hey, we're going to get you spayed soon, then you can meet him. Until then, you'll have to pout alone." Poor girl. She's out now, and she's just sniffing and sniffing and sniffing everwhere he's been!
