When you use the keyboard, pressing the up/W/enter key in front of a group of piggies results in a large confusing menu of the same exact looking pig, giving you literally only their names to go by in determining which one is which. It would be even better if a visual cue was available immediately for every animal that still needs harvesting from. I propose one of the following UI changes to the selector panel as follows:
Animals that cannot be nibbled, squeezed, or milked any longer will show up in greyscale such as this:

Alternatively, you could have their mouseover icons show up over them in the selector box like such:

Either way would tremendously help efforts to deal with our critters when we have soooooo many of them overlapping. It would help even more when we visit a street where all animals have the same exact name! It's quite impossible to deal with that as it is now.
