Discovered them in my son's hair!!! Baby ones too.
This isn't a nit, so what the hell is it?!
He sometimes plays with a kid from our neighbourhood, and sadly this kid is from a family who are not too fussy on personal hygiene and have 6 cats. Nice kid and all that, but from a dirty home unfortunately.
My son was playing outside with him this afternoon, then came in itching and scratching his head and I find these creatures in his hair 
I've done a quick Google image search of cat fleas, but it doesn't look like one of those either.
I'm worried I need to burn my house down...What is it?
