Expected:
The pet (p) menu item is active or greyed out to show me whether the plant will accept petting. Also, the heart and water-drop icons appear above the plant.
Actual:
Since there's only one menu item for a seedling -- pet (p) -- it's highlighted as the active item and I can't tell when it's had enough. I have to just keep petting it until I get a message telling me to go away. The icons don't appear for seedlings and juveniles.
Repro Steps:
Plant a new seed.
Pet it and watch...

See my action history at right. The context menu looks the same whether I succeed or fail...
