my holland lop is 2 1/2 months old and all of a sudden has been trying to get out of his cage (I have wire cubes put together). He also has been pooping outside the litter box. I have no other hay/pellets outside the litter box, he has chew toys, and a cement block for his teeth. He was successful one night in getting out and hopping all over the house when he has never left the living room before. He was pretty good when being out that he would go and poop in the litter box and I have now found poop all over the house. I do not see his testicles drop yet. Why the odd behavior all of a sudden??
