I can say with absolute certainty that we have two cats. We may have more, depending upon your definition of "have". If cats which hang around despite the fact that they aren't fed, aren't petted, aren't wanted, and are regularly threatened with being shot can be said to be "had", then we have four cats.

We also have a 1/2 acre pond full of koi and comets. Some of the koi weigh five pounds or more.
