About 4 or 5 days ago I noticed that one of my male cats has diarreah. It's not a pleasant sight to see in the litter box. I figured maybe he had worms because one of my other cats have worms. I ordered something off the internet, it was a multi worm pill. I followed the directions and dewormed all my cats two days ago. I thought maybe it would clear up the diarreah, but hasn't. I'm starting to worry because I am able to *hear* him when he has a bowel movement. Should it clear up since I gave him worm medicine? Or is there anything I can do to help with the dirraeah?
