yes, I have been treated before had them once as a child and once as an adult
not a nice thing to have
you will know about it if you do get them. if you'd like further info pm me i don't really want to post that kind of thing on here.
sometime no matter how careful you are (constant hand washing) it does tend to be minor contact (ie scooping litter) that can transfer the eggs.
Bare in mind also when a cat grooms it groom everywhere there's nothing to prevent the eggs being spread on their coat and aborbs by us when we stroke them but i reckon you would need to be in frequent contact with the cat.
you can get the treatment from a pharmacy - if treatment is required everyone in the household needs treating and it's second treatment is done again in two weeks.
