I have a bunny about a year in age, male, neutered.  He was well behaved, using his litterbox, and then a few weeks ago started peeing everywhere!  I have to totally wash his cage every day, and mop the floors every day.  I can’t let him on the carpet anymore.  He does not pee in the corners of his cage or the room, but everywhere and multiple places, multiple times of the day.   His cage is saturated several times a day.  He infrequently uses his litter box.  Diet or litter has not changed. He drinks about 20 oz of water each day.  When I catch him peeing I immediately pick him up and put him in the litter. I clean up the area and place a paper towell with pea on it in his litter box.  I hate having to keep him in his cage and am worried about how unhygenic it is for him.  In the morning his cage is a mess and he is usually huddled in a corner waiting for me to come and clean it all up.  Help!!
