Before I had my rabbit Bunny neutered at the age of 5 years, she built birthing nests. She built a birthing nest in the closet of our bedroom..she normally slept under the bed. I had to have our house fumigated for termites, so we all moved to a Marriott Residence Inn for two nights.. we took Bunny. After awaking on the second morning, we discovered she had built another birthing nest in a corner of the room. She used straw from her liter box and shredded up newspaper. She had very powerful instincts to make a birthing nest. We had her neutered at 5 years.
We took her with us for several week end trips. We'd take two litter boxes, one for Friday night, and one for Saturday night. She never soiled any motel room, she was very precise with litter box manners. ............I'm hoping that our now two Flemish babies will have such disciplined litter box manners...they are not there now, but pretty close!!
