I'm constantly in the nurturing grounds, I quite like to do so, but sometimes I find it quite tedious. I think that if it had a little page counter it would help greatly. The page you are on could be page one, then it would simply tell you how many more pages that are to come. it doesn't have to be on every category, but maybe "mine", "My friends", "players who nurtured my pets".

I also think it would be fun to add a whole new category : "Pets for sale"
i feel like it would be fun tabbing though all the egglings and hatchlings that people have up for sale

I think that it is fine the way it is. Before nurture grounds, nurturing was done via peoples hatcheries or advanced search. We are lucky to have the nurture grounds that we have
