My cats and I moved back in with my parents a while back and a couple days ago I noticed worms hanging out of my mom's cat's butt (sorry I don't have a better term for that). I called the vet and described the worms and they said the cat has roundworms, so I went in and picked up an oral dewormer for all of the cats (5 total). I gave them all the first dose, and the next dose is in 2 weeks. My mom's female cat is the only one that we actually saw worms on, so we're watching her like a hawk, looking at where she regularly sits. She has a pillow she sleeps on every night on top of my dad's dresser, and my mom came out and said there were little pinkish things all over the dresser around the pillow. These things are about 1/2-1/3 the size of a grain of rice, and they kind of had a really light pinkish tint to them. The only thing I can think of is that they are roundworm eggs. Does anybody know? We through the pillow in the washer and sanitized the dresser, and washed my parent's comforter. Actually, now that I think of it... I checked the cat tree for worms, but I should go back and check for eggs.
