Not implemented and probably won't be implemented soon, with the size of our backlog. It is unfortunately kind of complicated to implement and I am not even sure if it's possible yet in the current system for how items like that work. But if it makes you feel better, staff would be in support of this suggestion, just not sure about feasibility.

One thing we could implement sooner though, if people would like this, is to have it randomly change to male or female, instead of defaulting to male. It would be nice to remove the "male as default" from it, and then you'd at least get a 50/50 chance of getting the gender you wanted, instead of always having to use two berries if you wanted female instead. What does everyone think of this idea?

[edit] I mean random for genderless pets only - it would still work the same otherwise!

So actually it was pointed out that the Official FAQ says it should change it to a random gender, which implies that's how it's already supposed to work and if it's always changing to male maybe that is a glitch? I will check with on whether a fix needs to be done for this.
