I have 21 barn cats and they are pooping Diarrhoea and can’t control it I don’t know if all of them are sick because some are wild but most of them are sick and it’s been like a long time and then they’re just not getting better like probably a month but like some of them probably have it for like over a month but it comes and goes sometimes it will be normal and then sometimes it will be like really watery like bright yellow. I've researched alot of things it could be but one or 2 we believe

Thanks for using Petco Pet Education Center, formerly Petcoach! It sounds like an intestinal parasite. In a close area it is easy for parasites to spread, especially if the cats use the same area to go potty. I would recommend taking 1-2 cats to the vet and bring fresh poop samples so they can look with a microscope. If none are found, they may need to send the sample to a lab to look for a more rare parasite called tritrichomonas. This is usually found in a larger cat group and can come and go but it isn’t as common. Once a diagnosis is made, they may be able to get medications to get the cats treated. I would also clean up stool as often as you can to decrease spreading and clean littler boxes with soap and water daily. Good luck!
