BACKGROUND INFORMATION
I have two sisters.  When we were very small, the first word all of us learned to say was "kitty."  It should come as no surprise, then, that all of us have multiple cats.  My older sister's count usually stays at just over 20 (click here to visit them).  My husband's family has cats also, so he's no better off.
All our kitties who are old enough are neutered/spayed and all were former strays or "dumps."  They are indoor cats and do not go outside unsupervised, though we do let them out to play in our walled-in garden area every morning and evening.  We keep an eye on them while they're out there so they don't go over the wall.  Tamerlane will wear a harness and enjoys going for walks occasionally.
My husband and I seem to wind up giving our cats both "given" names and nicknames, and frequently the nicknames bear no relation at all to the given names.  Multiple cats with multiple nicknames creates some confusion among friends, relatives, and veterinarians, but we manage just fine - as do the kitties.  On the cats' pages, I will mark with asterisks the name(s) each cat uses most frequently.
MEDICAL CONDITIONS
We have encountered numerous feline medical problems - more than seems normal even in a large group of cats.  Some of them have been fairly common cat problems, but a couple have been rather odd. 
Each cat with a significant medical history has his or her own "medical" page detailing symptoms and the way we dealt with the problem.  I'm hoping this information may prove to be useful to others.  If you are interested, click here for a summary of which cats had which illnesses and symptoms, or use the Medical Index button at the bottom of this page.
BISCUITS
You'll see references to biscuits and making biscuits on all the cat pages.  Making biscuits refers to the kneading motion cats make with their front paws when they are happy, which looks sort of like someone kneading biscuit dough (the American kind of biscuits, which are similar to scones).  My family has always used the term and many people who know us have adopted it.  For a long time, we weren't sure if it was a genuine Southern American expression or something my father's family came up with, but since we've seen it used elsewhere recently, we're assuming the former.
A BRIEF HUMAN HEALTH NOTE
Having pets is supposed to be good for your health, but I wonder sometimes when it comes to cats.  I tend to get muscle spasms in my neck and lower back, so I bought a specially-designed pillow with an indent in the middle.  The indent is supposed to keep the neck in an optimal position and so help prevent muscle spasms. 
If the people who manufacture these pillows had any sense, they'd start slapping leopard-pattern covers on them and selling them as cat beds.  That indent in the middle is apparently the ideal sleeping place for cats, and there is fierce competition over the pillow as a result.  Jessamyn was the most stubborn.  She used to sit on my head until I moved.  I usually end up using a small area on a far edge of the pillow with my head in an awkward position, while a cat sleeps soundly, curled up in the middle.  I've never heard of a cat having a neck spasm.

Now, on to the cats.  I only wish the In Memoriam section were not so large, but it does go back a significant number of years.
