I Am a Cat Lover [Cats]

Hi all. My wife and I are cat lovers, and we have 6 cats. We call ourselves 'foster failures'. We say that because we were fostering some cats for a while, but the trips to pet adoption days we were bringing them to began to get too taxing, so we adopted them. The cats' 'litter box' is actually a 24 gallon Rubbermaid-like tub that we fill with the 35 pound plastic jugs of litter. I scoop it twice a day.
