Found this. How does it square with conventional wisdom that cats
should not go without food for more than a day or so?

http://www.felinefuture.com/nutrition/bpo_ch9.php

"Fasting
It is very beneficial for healthy adult cats, to withhold all food for
a 48hour period on occasions. This extended fast will enable the body
to clear some accumulated toxins from fat tissue, and completely empty
the bowl. Healthy cats don't fast voluntarily, but are frequently faced
with an involuntary fast in a natural setting through unavailability of
prey, or repeated unsuccessful hunts. They will, however, frequently
refuse food when unwell as a possible means to speed recovery. Cats are
unharmed by the absence of food for several days, and in extreme times
of famine may loose up to 50% of their body mass and still survive. It
is, however, critical that the cat has unrestricted access to fresh
water during fasting."

Again, what do cats naturally do in the wild -- if they fast naturally,
then fasting is good.  If they don't, then it's not.

Cats in the wild have no choice but to fast.  Do you honestly think that they
would fast in the wild if they had food available 24-7?  No, they would eat
it!  By the way, our cats are not wild animals, they are domesticated.

It's done with the big cats, but I don't know if it is a good idea with
Felis.

When I worked in a vivarium several years back, I worked the "cat house" for
a few months.  It was standard procedure to withhold feed every Sunday.  The
official reason was that it was healthier for the animals to fast for 24
hours.  Doing this on a regular schedule reduced stress to the cats because
it didn't occur unexpectedly.  Of course it was also cheaper too but
compared to the money spent on housing and environmental control one day of
feed was insignificant.  Other than Sundays food was provided ad lib. and
clean fresh water was available at all times including Sundays.

According to the early scientific literature on longevity in regards to
Caloric Restriction and Adequate Nutrition or CRAN, by Walford and
Weindruch, animals fed every other day lived far longer than animals
fed every day. But whether this would work specifically for cats, I do
not know. The animals fed restricted calories, that is low calories,
lived even longer than those fed every other day. So far, the last I
read a few weeks ago, it appears to be holding up. And a recent study
appears to support CRAN for humans, at least in the short run of a few
years going by a reduction in diseases.

Oh hell.  Does this mean that I would be healthier and live longer if I were
not over weight?  The next thing you'll tell me is that drinking a case of
beer every week end can adversely effect my health.  :^)
Seriously though, do you know if there is a web reference to the study you
cited?

No but I paid attention to it and can tell you the essense, The study
was extremely misleading.

Suppose you buy a machine, but never use it, just do minimal
maintenance. Then it will "last longer" because there is no wear and
tear. But that defeats the purpose, usually we talk about a long
lasting machine we mena to be able to *use* it longer.

Similarly, our bodies are machines too. If you don't really live (no
work, no emotions, no sex, no enjoyment), just vegetate with minimal
maintenace of survival functions, then you too can last longer. That's
what they found. If you cut down calories so much that the body is in
maintenance survival mode but doesn't have energy to do anything that
will cause any "wear and tear", then the body will last longer,
essentially as a vegetable. But is that any life, for you or your pet?
I'd rather we live normal lives and go when God calls us.

So the people on this site think know more than veterinarians and animal
scientists?  Neither vets nor scientists recommend fasting your cat.

When your cat goes to the bathroom, his bowel is completely emptying.  Just
look in the litterbox and you'll see.  Ridiculous logic.  Cats in the wild
have no choice but to fast if they can't find food.  

>Cats are unharmed by the absence of food for several days, and in extreme times

Obviously they know nothing about hepatic lipidosis:

Never fast a cat.  Period.

Sorry for the delayed reply. I'm buried in kittens and I've been busy
breaking laws prohibiting feeding ferals.

Feline Future has some good information but they tend to be a little
extreme- if not a little fanatical.  I don't think you'll find many
mainstream vets or vet nutritionists that would encourage unnecessary
fasting.

One of the towns passed an ordinance: $2,000 fine for feeding ferals!
Next they'll be calling in SWAT or declaring martial law.

The city counsel of bureaucratic buffoons voted against TNR based on bogus
myths and misinformation and completely ignored all the data that proves TNR
works including vet journal studies and testimonies from ACOs of other
towns.  The original hearing notice was a tiny two-line ad buried somewhere
in the local newspaper.  I think their decision was strongly influenced by a
couple of slimy, local vets that were afraid they would have to perform
low-cost neuters if TNR was adopted.

The city attorney is as inept as the slimy vets, he drew up the ordinance
with more holes in it than a hurricane fence- and one, especially huge
gaping hole that I'll drive through with a truck every day- twice!  I wish I
could tell you more but I can't right now.

Yeah, God forbid they should help the homeless pet/feral overpop
problem...I just totally do not get this mentality.  One thing I do
admire about the main guy I worked for is he did low and no-cost S/N as
a routine service.  He probably generated more (side) business for
himself that way, and retained more clients than any other vet in the
area.

Well, if I ever need help jumping through loopholes, I may just email
you!  So far our city has been cooperative <knock on wood>.

How do you distinguish a feral from an outdoor cat?

Someone I know has a cat that hangs around her property. She feeds it
regularly, and it spends most of the day hanging out in her yeard. (It
cant come indoors because her kids are severely allergic.) While it
started out feral (or probably lost or offloaded) it has adopted her
and vice versa.

So legally what makes one cat a feral and another an outdoor pet?
