I have cats and occaisonally get scratched - I always douse it with Prunella extract and then turmeric, doesn't get infected. But I've seen cat scratches cause very bad swelling and infection, treated a kid with one once.
Regarding toxoplasmas - I don't have a cat box, cats just "go" outside (5 acres) so I don't contact it. I've always lived where cats can just go outside. Cat boxes are ewwwww. If I lived in a city (horrors!!!) I wouldn't have a cat.
