Cataracts
As previously stated the Abyssinian breed is the one most
prone to this condition but other breeds can suffer from them.
There is no known cause for these and consequently no knowncure
but as they are more common in older guinea pigs it cold be
part of the aging process. They do not render the guinea pig
blind, leastwise not until they are very elderly. People I
have spoken to who suffer from them say that it like looking
through a veil.
The cornea of one eye becomes opaque and usually within a
month or so the other eye follows suit. The good news is that
guinea pigs who suffer from this condition seem to take it
in their stride and simply carry on as normal. I used to give
a supplement of vitamin A but no longer do so. After observing
other people's guinea pig with this condition who were not
on this supplement I came to the conclusion that they coped
just as well as my own. Though I am a strong believer in the
value of supplements for as therapy for specific ailments,
if they can do without, all the better.
