@Fox- Doesn't mean that, if you personally find no use for it, it'll be no use for anyone else.
I have some pets that I like better as teens than adults, or teen pose fits them better, and I'dlike to keep them that way in my profile. For example, Nehaher x3 teen pose just fits her character perfectly. And she's a very loved one (my profile's based off her anyway...), so I'd really want to have her in my profile, but that'd mean having to find someone to zap her every 15 days.
I don't think this really defeats the purpose of the Rray, as broken said. Most people use the ray to zap pets adult because they aren't patient enough to let them age xD *like me for example...*
