She has diarrhea and earlier this week the vet had me give her 18# brother 1/2 tsp. every couple of hours until it cleared up and next week I'm supposed to get a deworming and flea solution to put on their backs. They are inside kitties and big so normal flea treatment at the back of the neck just sent the fleas to their tails. They got the fleas from a friend's visiting dogs. Anyway his was bloody, herself is not yet and I hope to avoid that(although I don't think there was any warning before his went south, I think it started that way.)
