What, you mean they actually stop moulting ...? :roll: :lol:
Mine were a mess, like yours (the neighbour asked what was wrong with them!) but now their fur is all one level again but they're still losing clumps out their bums - though the fur level has stayed the same. In the summer they had the thicker fur which was coming out in chunks and looked a mess, but they also had a smoother, shorter length fur. As I say, it's all grown back now though they still look a little tatty around their bottoms. I love plucking it out if they stand still long enough; it still comes out in sheets if I get the right bit, but no "bald" patches anymore.
