I think when you hatch a pet it should remember the gender of that pet. So for example I happen to hatch an albino male zenirix but gosh darnit i accidentaly opened the human avatar page and my computer froze causing me to close my browser. When I log back on I go to the hatcher and it just days Congratulations you have hatched a albino zenirix. Now what was the gender again?
It would be sooo helpful if the gender just stayed there even after you hatched your pet and navigated away from the page. I'm sick of having to put random names on some of my pets. It's annoying and I think a girls name on a male pet also brings down its value so it will be better for the res economy lolololol.
