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.
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
Cloth baby diapers make great cleaning cloths no matter how stained they are
