Honestly I think that if your leo is gaining weight and increasing in size that you should have nothing to worry about. Aslong as they shed (we may not see it all the time, but if s/he is getting bigger that means that it is shedding), then you should have nothing to worry about. Usually the light purple bans turn to dots as they get older. My male was spotted a little with high yellow bans and some purple bans and as he gets older the only color really i notice is the purple fading just a tade and turning into dots, some do do this and others dont. Dont stress until it loses weight or stops growing, if its a year old it should be about grown completely. How big is it length and weight. dont stress to much ok
