My kittens are acting happy and healthy, however one of them had fresh (red) blood in their stool. although i have 2 litter boxes they both use the same one. I called the emergency vet, and they suggested i watch them to see if i can figure out which one it was. I had a vet appointment Tuesday to get their shots although they were seen last week for a deworming and checkup. i am worried... and they seem to be oblivious that anything might be wrong and neither is acting sluggish or sick. their stools were both a little watery but they have primarily been eating wet food... i keep the dry out but they prefer the wet. I have been feeding them Authority Dry food and Nutro Max and Nutro Natural Choice... I really can't sleep now... i wonder if anyone has any idea what might have caused this... they have been with me for about 5 days now...
