I have 7 cats in one room while medicating them. 6 are ferals and one is a rescue. I was cleaning and found a streak of blood in ones potty. How will I know which one it is and what could it be? I have wormed most of them. Some I can't touch. I saw worms in ones potty. She went while I was cleaning. I have wormed her 3 times. But I saw no blood. Is there signs other than blood that would let me know which one is not doing well. One is still sneezing and has red eyes. They keep passing the uri back but I only have 4 cages and I let them play together all day. They are really noisy if I leave all 7 running all night. I have no other rooms to keep them in. My cats and kids have the rest of the house. They seem to be doing okay other than that. Playing and eating. They have been throwing up some though. Not sure which one on that either. It is not like with my cats. I know most of what they do. I will try to keep an eye out on them but if you have advice please let me know
