Squiggler, would this maybe enable you to click on a button on your pets profiles (for example) and see the past generations? I would kinda like that implemented as well...
It would be a nice add on to have, and it would definitely mean that people would enjoy the breeding aspect more as they could keep track of the past generations and, I don't know... breed 'pure blooded' pets. (Whatever that would entail on your site, either breeding with only that one colour or type... whatever
)
