I am astounded over how many people get rabbits from others wihtou being told they are pregnant, or simply lied to about it. My daughter's friend couldn't keep her rabbit anymore, so my daughter begged for us to take it. I held it and it's nipples were distended, and it was doing the "hey, I'm bred" growl. I asked the mother if it was pregnant...oh, no, she's our only rabbit. I asked if she had been with any other rabbits, and she said, yes but that was well over a month ago, and if she were pregnant, they would have known. Then why, when given a box, just in case, is she making a nest? If I had just ut her in a hutch, without listeing to my intuition, we would have had another baby-on-wire mess to deal with.
