How Many Cats Have You Ever Had At One Time?

At one time I had 13 cats in my home. That was when I realized I had a potential problem and was on my way to becoming a cat horder. I immediately found homes for all but 4 of them. Litter box smell was a real problem when I had so many. We had 2 bathrooms with a little box in each. The rule was, that whoever went into a bathroom for any reason scooped the box. That did help considerably. Once I narrowed the fur people down to the 4 cats, it was much easier. Plus I had a dog at the time, too. Now I have no cats, just a little 10lb fur ball of a dog.
