Nope. It's the appropriate containers (chosen 'by species' from the habitat menue) and what happens is I click on the dish/item (food dish for pangolin in this case) and it switches from 'inappropriate food item' to 'suitable food item' but doesn't 'stick' ... when I click back on a few seconds later it's back to inappropriate (and switches to suitable, ad infinitum). At this point, there's only one feeder that the keepers are filling and it's not enough to feed all the animals so I've had to move them to the trade center. The keeper hut is nearby and they're properly feeding animals in habitats further away.
