I am still in shock at how many cats you've had at once. 18?! I don't know how you do it. If fleas or other pests begin to take toll, what do you do? It just seems so hectic. But it must be wonderful to have 18 cats giving you unconditional love throughout the months -- whether they are yours or fosters.
I live with five cats. It's the most that I'll have and the most I'll ever have. It's so difficult to clean with five cats shedding at their own pace. So I commend you in being able to keep a clean environment with 18 cats! But one things for sure is that I love the amount of personalities I am able to spend time with. My cat, Wolfy, is mainly independent unless he chooses to cuddle, Timmy loves to cuddle, Muzzy loves to meow, Benjamin loves to play hide and go seek, and Vie loves to just meow and get into your face. Definitely a great spectrum of cat traits to spend time with.
