Even after my objections, my DW and DD1/2 brought home a stray kitten about a month ago (I really have control in my house, this makes 2 cats). They promised it would be gone well before Christmas, but the tree is up and the cat is still here.
No ringworm or fleas as the cats do not want to go outside due to the cold/snow, we will see what happens in the spring.
