I have a set of 4 week old rats i weaned them a few days ago but when i looked at them this morning they don't look right ? They are really pink and looks like they have less hair . I wonder if i weaned them to soon or is it just me today LOL . I have had a lot of litters but never noticed this before . They are alert and running all over like the rest of my rats but they kinda look goofy to me for some reason today ! Just wanted to see if anybody else has had this happen ?
