So, I was browsing on Sylestia as usual and saw the common stable space problem. This led me to another suggestion.
Is it possible to remind you that you only have a few more spaces in your stables, say, 5, and you have 10 eggs in your Hatchery? Then, it'll say, "5 Random Pets Will Be Released If You Do Not Buy Stable Space" with the "Add More Spaces" button underneath. But this condition only goes for if most of it are Adolescents.

That was unclear

So, what I'm talking about is just
Say I have 10 Sylesties in my Hatchery. 7are Adolescents. AndI only have 4 more free spaces. This will only pop up if the number of pets that are going to get released are more than half of the stable space.

Now, the message ("6 Sylesties will get released soon! Please buy more stable space to prevent it.") appears. I can choose to Ignore it, or click on the Buy Space button.

Note that this message will also only pop up if more than half of the pets are Adolescents

This is just an addition for people who have a hatchery of cute themed babies, thinks they have enough place and*tear rolls dow my heek* It's pure tragedy. And for them diamond-less people, who are unable to reclaimT T
