We go through 1-2 gallons per week cleaning litterboxes, enclosures and floors
Some of ours are 3 years old and the washers and balls are going bad. We have over 50 cages and each has 1-2 water bottles.
Carefresh is the best, but also the most expensive. We would use 5-6 60L bags per week just for the rabbits.
We like to provide a rug for each rabbit, and the bathroom rugs seem to be the perfect size.
We purchase supplies from many different stores.....Home Depot, PETCO, Randazzos Fruit Market, Meijer, etc.....
These are used for washing vegetables in the washing machine, we go through 3-4 per month
