i have 2 cats that need prednisone...5 mills a day.
but i weeded it down to half that a day recently.
i think 8 mill's won't kill them....accually i know it won't.
my vet had to give one cat 10 mill's to stop his coughing in a shringe i think.
it was a long time ago so i forgot if he said 10 or 20 mill's....his cough was just terrible!!
but i'll say 10 to be safe...don't worry
