Allright, I finally get Xander all healthy and happy, now his formerly tough and healthy brother Bo, has had an incidence of diarhea with a trail of blood in it. He has never had the runs before, or blood in any poop. He is is little more restful than normal, but that can happen on any given day due to the weather or a long night running around. He's still eating and playing and wanting to be in the way, but I really don't know what could have caused this incident. Speak of the devil, he just appeared at the door. Maybe he may have just eaten a carpet fiber from his clomber or a little fizz from the floor. Who knows, what can cause this reaction in a 4 month old cat? We have the house cat proofed as much as possible, what have we done wrong? -Jess
