Cats?

Kim and I have planned for years to get a cat, so now that we have our own house it seems to be time. Shortly after moving in, we visited the neighbors and saw their two cats playing together. This inspired Kim to upgrade our plans to two cats instead of one, and I had to agree with her: that way, the cats can keep each other company when we're both out of the house (or when we're out of town). Things seemed settled.

Today, we visited a fellow faculty member who has a local cat rescue operation. She has a bunch of kittens (and a few older cats) available, all of which are adorable. Among them is a set of three sister kittens who love each other ever so much. So now Kim is suggesting that three isn't that much larger a number than two (and I certainly share the temptation).

I'm a little nervous about where this is heading. :) But in all seriousness, for you cat people out there, how do you think three compares to two?
