Need some help with pet feeding boxes

#1

So I have a pet feeder full of fibre bark and berries, right in front of my Rhinos. Do the eat from eat like normal animals no they dip into my spiders food box instead. My Rhino’s are flesh eaters now.

What gives how come they are not eating proper food? I also found some of my cats eating weird things as well. Is there a problem with how the boxes push out food?
