Gus so nicely demonstrates the difficulty of oddly shaped items. When full this object can be quite heavy making it difficult to manipulate. For Gus it is no problem! Eating this way has helped Gus loose weight. Please share this video if you know an overweight kitty who could benefit from learning to forage for their food.
Gus is one of the kitties featured in the table of the paper we co-authored for the Journal of Feline Medicine and Surgery (JFMS).
