My 60+ pound dogs can lick a dab of peanut butter off my finger in one swipe. The same amount placed on one of these lasts much longer--up to two minutes in some of the grids. My 10 pound dog who is ancient sometimes licks her feet compulsively. This distracts her. Use with goat's milk, cottage cheese, broth, cream cheese, even dog toothpaste!Before buying this, our kitten would race through only eating the middle of the bowl. Now, even though he attempts to eat everything, he has to come back later because of how tired he gets.It's super easy to clean and spread the food. The suction cups at the bottom keep the tray from shifting from all of his excitement.Great suction on any flat surface. In fact I have to put them on a towel while spreading the treats so it doesn't stick to the counter. I do not see the purpose of using these for a "slow feeder" but for a licky mat it's perfect. Only complaint is they are not the easiest to clean. To be fair any surface like this would be hard to clean. I suggest to clean the mat off with a small sponge and brush immediately after your pups are done. Once any remainder treat dries it will be harder to get off and bacteria will grown. I have made the choice of not putting the mats in the dish washer. Silicone over time will break down due to constant dishwasher use. I don't put any silicone products in the dishwasher.My cat eats way too fast and throws it all up. This has helped with that. I will say that the large patterns are quite shallow (each fits 1 cat kibble) so I can’t fit much food on here.These are filled and frozen as part of my dogs routine for bedtime. They each get one when they go to lie in their crates and it helps them relax at night. I don't use the suction but when filling the suction get stuck if I don't put them on a towel so I know it works! They can be filled with so many items and I like to use each of the 4 areas for a different taste It can be such a small amount but when frozen keeps them busy. I use meat baby food, yogurt, scrambled eggs, cottage cheese, squeeze cheeze, liverwurst there are so many options! Recommend for a treat for your fur babies!They were great! The suction cups worked well and kept it on the floor when my more food-focused dog bit it trying to bring it up. Would definitely recommend.This works great for keeping our dogs occupied while we brush them out. They actually stay in place to be brushed. We mash a little bit of cream cheese down into the grooves so that they have to work at it. If we freeze it first, it keeps them busy even longer. I put it on the front of the refrigerator, and that usually works well. Sometimes it slips off, but I think if I wet the suction cups first, that may not happen. Overall, I am very happy with this purchase.I love the variety in the groove shapes.Lo único que no me gusto del juguete es que necesita una superficie muy muy lisa para poder pegar las ventosas. Es un excelente juguete para congelar con yogurt, crema de mani o algo similarMe encanta que tenga diferentes figuras
