My son was at the flea market Friday and someone had a box of kittens. He texted to ask if he could have one and while waiting for a reply he was holding one. The guy with the box walked off leaving my son and someone else with a kitten. Vet says he is 4 weeks old, not even fully weaned.
I was only making a stupid joke because you got him at the flea market, but it's still good to be careful. Our cats had a nasty worm problem for a bit due to fleas.
