My 5th house is ruled by Leo and intercepted by Virgo. I've worked with children a lot and relate to them well, and I love cats and relate to their nature, usually. Dogs can like me too but I'm not experienced with them so I don't quite know what to do.
I have many planets in the 6th house, the house supposedly for small animals/pets.
Animals are instinctual and have heightened senses, for survival purposes. They can probably sense that you're a good person that doesn't mean any harm. Children probably gravitate towards you as well.
