Ok I am officially disgusted! And concerned...I have 3 cats, all indoor now, 1 old, 2 new rescues. All have been dewormed before taking them home. I have no clue which cat it is, I know it has to be one of the new cats, but I'm sure they will all have to be treated now. From the pictures on the internet it is roundworm, I also found one in poop in the litter box. If anyone has had this problem before, how did you successfully take care of it? I also read that roundworm can be spread to humans. These cats jump out of the litter box and get litter stuck in their nails, and then litter ends up wherever they jump, like on a bed sometimes, as much as I run around and vacuum and clean, it still happens. I'm usually home all day so as soon as one uses the litter box I clean it out, it's never dirty, unless I'm out for the day. SO I'm kind of worried...I have kids in the house, who run around and roll around on the floor with these cats, and one cat sleeps with my youngest daughter, and she has had to brush off litter from her bed, of course we change it anyway but I'm sure she touched it already, how easily would a kid catch it from situations like this? I've had cats forever, but never worms, the thought of that never crossed my mind until these rescue kitties came along, and now...we have a worm situation. Just the thought of worms is making me insane! I'm taking the cat that is the most likely the victim to the vet tomorrow, in the meantime, I need to know how easy this is to get and what is the best way to keep them from not returning after being dewormed (again)???
