The rabbit hutch plans should be made so as to consist of the necessary space which is much need for supplying these kinds of items and also toys that will help the rabbit to stay fit and active all day long. It will be a good idea to make the flooring of the hutch with wires that will allow the droppings of the animal to fall down without making a mess within the area. This type of inclusions in the rabbit hutch plans will make it a more convenient tool for you as it will enable you to clean the cage easily and without handling too much of dirt.
But this type of wired flooring also has one drawback as there are certain small species of rabbits like the Rex and the Mini Rex whose little feet may get entangled between the interwoven mesh of wire. What you can do is to include a grass like mat in the rabbit hutch plans. It would not only give a grass like feel to the animals but you will also have to wash the mats to make the cage free of dirty remnants.
