Yesterday two of 5 kitties developed scaly bumps on their heads. Looked like cradle cap, but I wondered if it could be scratches from sharp claws as they play quite roughly. Today, two more kitties have the scales. When I scrape off a scale, the skin underneath looks perfectly normal...it is not red or irritated. Otherwise, kitties are eating great, exploring, and very active. Does anyone have any ideas about this? Just wondering if it is a normal kitten development or something more. Thanks in advance.
