Disappointed! Ridges too shallow for dry kibble!

My high hopes were dashed with the mat for dry kibble and treats. Due to the fact that the mat depth/ridges are far too shallow, they did not hold the cat kibble in place in order to provide any kind of a challenge for slowing down eating. I also tried some very tiny treat gravel and my cat was able to eat the kibbles d directly with no challenge at all. Her main diet is Science Diet Hairball formula kibble.. I did not try out the "wet" food mat. The home-made food that I cook-up is not fine like pate. My animals prefer a more robust food with texture to it.My cat is very small for an adult cat, only 81/2 pounds, as well. I feel that I should be given a FULL refund! The designers of these mats need to modify with a much deeper profile in order to match up with the recommendations.
