Hi guys. Our little girl Astra has really fuzzy ears! Her ears are covered with fur, not the baby fine hairs she has on her body but not full blown fur either. And she has tufts of hair on the bottom of her ears where they join to her head. She is 6 months old now and is fixed (I read that could make a difference, but in the opposite way!). She also has a pretty fuzzy/furry tail. Is this common?? I've read somewhere that if they're too cold they will start to grow hair!! Is this true?
