I have had this guy for about a week and tonight I noticed a scrape or whitish bruise on the top of his head. I honestly am not sure if it was there when I got him or not. Sorry I do not have pics, just wandered if they commonly scrape their heads on the screen-top, or other rough objects in his habitat. I have not seen him act strangely or anything (like some neurotic TBR's). Should I have him looked at or just monitor it? Thanks.
