My neighbors litter is approximately 2 weeks old and have just started to jump out of the box. She noticed a very thin lining of green/yellow around the nostrils of each REW kit (doesn't notice it on her colored kits). I wouldn't describe it as "crusting". The kits seem fine so far. Are these linings normal?
