Fits
If you see a guinea pig have a fit, usually after a frantic
scratch, nine times out of ten it means that a fungal skin
complaint as not be diagnosed early enough which has advanced
to become systemic.
The guinea pig will roll over onto it's back, the whole of
it's body will shake for a while then it will arch backward
and stay still for a couple of seconds then flip over onto
it's feet and get up.
The first time owners see this they think that the animal
is having a heart attack and if the fungal infestation is
not cleared it could lead to this eventually. However, this
kind of fitting can carry on for quite a long time before
they have a serious effect upon the guinea pig.
Let the guinea pig come out of the fit in it's own time,
then pick it up and nurse it for a couple of minute before
you check it over for the fungal problem. See Skin problems.
There are fits that can be caused by neurological problems
but it would take a far better expert than I am to give the
causes and suggest remedies, if there are any.
