Liki mats are perfect sensory activity for keeping dogs or cats guessing and engaged.  This wobbly bowl with a bobbly surface is a good challenge for a busy mind and brilliant for reducing stress.  You can use the mat over and over with a little wet food, some of our tasty liver paste or some peanut butter (the dog/cat friendly kind).  A great idea is to wet the bowl and then sprinkle some salmon crunchy powder over it, which gets into all of the crevices and offers hours of fun.
