Reply #7: I have a friend who has a dairy farm

[harper]

And they have tons of cats...a cat colony as a matter of fact. She'll have several litters at a time. The mothers all nurse each other's kittens with no problem. However, all the kittens have the same father...the dominant tom. When he (the dominant tom) came onto the scene several years ago, he promptly killed all the kittens that had been fathered by the previous tom. And when is supplanted, the new tom will kill all of the current toms kittens.

Now my friend wants a lot of cats so she doesn't get the females spayed. She does make sure all of the pregnant females get wormed and have their shots, and she keeps all of us who know her in pet cats. My panda (a Siamese mix) came straight off the farm.
