I've been taking care of an outdoor cats for about 5 years now, and in recent months also of a mother cat and her 6 months old kitten. they mainly live in my yard. I've been petting and cuddling the first cat for years, and I also do the kitten because she's friendly, they like to sleep on my lap/chest etc. now I wasn't too much knowledgeable about worms and parasites (only that they exist) but recently I noticed the mother cat (I don't touch her since she's not friendly) has what I think are tapeworms ( I saw a little white worm moving on her anus) it made me dive deeper into the subject and research a lot about it online, I understand humans can get infected by worms from cats as well, and some type of worms/parasites can actually have severe health effects on us, which all scared me quite a bit. I don't really cuddle the first cat anymore, the mother I don't touch at all, and the kitten (which I do cuddle) I give anti-flea spot ons, but ultimately they are still outdoor cats. I understand humans can get infected by having contact with contaminated feces or soil, and then have hand to mouth contact, while I do always make sure to never touch my face when I'm outside with them, and to always wash my hands throughly when I go back inside, I do not know what kind of invisible traces of soil/feces they may have on their fur, and since the kitten and the other cat sometimes sleep on my lap/chest and touch my clothes, it makes me very worried about my safety, because I'm undoubtedly unawarely touch my clothes and then my face/mouth throughout the day. So my question is can I be infected that way? from their fur to my clothes contact and then hand to clothes to face/mouth contact? If so how big of a risk is this? should I stop petting them/let them sit on my lap entirely? or am I overthinking this? I'd greatly appreciate help on the matter.
