I know it's possible to have pet and minion overlays, but what about gender overlays? I mean the little image that shows the male or female sign.

As far as I know you can't, but I'm not an overlay person so I'm not 100% sure x]

I'm sure you can overlay anything, you just have to be able to code it.

I don't believe there are rules surrounding overlaying pet gender either... Might pay to double-check but i think it'ld be alright o.0;
