We couldn't hide it from him anymore. We were walking in the door the other day and I forgot to put Mal in my bag and he saw...*gasps*...our rabbit Chuck!
Don't worry though, he was a brave bear and was willing to hang out about five feet away from him so I could get a picture, after much assurances that Chuck couldn't get out of his cage unless with let him out, and we don't let him out very often since I have developed a horrible rabbit allergy. Yeah, I didn't know they existed either. With our reassurance, Mal feels very safe, even though he now knows there's a big floppy bunny in the house.
