how do you do it?

Hi again everyone -- My experience with Mr. X the Mystery Cat has put
me in touch with quite a few animal rescue people, most of whom seem
to have many many animals in their care. I find myself wondering how
on earth you manage? I mean, I have four cats and am at my absolute
limit of the number of critters I can care for, yet I read about
people who have 20, 30, even hundreds. I am awed by the obvious
committment taken on by these folks. How is it possible,
logistically? Do most of you with many animals have jobs, or is
rescuing a full-time thing? How do you keep so many animals -- do you
have pens, kennels, etc? How on earth do you pay your vet bills? I
just find myself curious about the logistics. I know a couple of
people who do animal rescue, one of whom has over 20 cats, and she has
built an enclosure for them, and of course she is a full-time rescuer.
I run my own professional practice, so that accounts for quite a lot
of my time, but I'm sure there are rescuers out there who also have
full-time jobs... how do you do it? I'd love to hear your stories. --
