I haven't brushed mine in almost a week. But luckily, they haven't developed any tangles.

Both of my boys are excellent with brushing. It's the nails that they don't like. I found myself getting peeved with Kaedyn once and after getting mad, I told myself to try making it a more enjoyable thing and you know what? It worked. He stopped trying to bite but he still tries to escape. It's nice not losing a hand though..lol.
