My white cat has developed a darkening of her nose (see other
post). I'm told white cats are prone to skin cancer.

I never let her outside but she does lay in a sunny window in
the morning for hours. The window is a double, with a storm
window on the outside. Doesn't that block the dangerous sun
rays or could this be the problem?

My hard-core feral looks almost like an albino, not white fur, but
you can see her skin is pinkish. Yours is a good question IMO but
somehow I doubt you'll find much information on the subject. My
skin (and eyes) is sensitive to the sun. And it never forgets.
Doesn't matter how long you stay out of the sun after you've had
too much. It's a cumulative thing though, so getting out of the
sun does help avoid further damage.

In case you haven't heard... Cats enjoy the outside sounds. Buy an
infant/baby room monitor and put the transmitter outside (out of
the rain). If you can, hook the receiver up to half decent
speakers (but the crummy built-in speaker would be better than
nothing).

Good luck and have fun.
