Package Dimensions ‏ : ‎ 4.3 x 4.3 x 2 inches; 5.11 Ounces Note: 1.The slow feeder insert is not a chew toy, so please try to prevent pets from chewing it - especially pets with habitual chewing issues. 2.Dog bowls with a base diameter of less than 4.7 inches are not suitable - they will cause our suction cups to not be firmly attached to the dog bowl. The Slow Feeder Insert is the perfect solution for slowing down your speedy eater. Just adhere your spiral feeder with its octopus suction cups to your existing dog bowl or raised dog bowl, add your desired treats or kibble, and your dog will slow down to capture his dog treats – no more gulping and choking. Any dog will enjoy a slow feed bowl, but the design is especially useful for dogs who like to use a snuffle mat for foraging for their treats under the soft arms. After professional market research and dedicated research and development, we have solved the major drawbacks of slow feeder inserts on the market: a. The base is not solid, and easy to be plucked off as a chew toy (we use higher cost better effect of octopus suction cups) b. loose blades and simple structure cannot effectively slow down the speed of pet feeding (we use a fixed blade and silicone nail design.) c. Hard, plastic material may hurt your dog's nose and is not environmentally friendly (we use food-grade silicone material, which is soft and does not contain any harmful ingredients) d.Our slow feeder insert is designed with cuttable tick marks, so it can be cut precisely to fit small, medium and large breeds of dogs. It makes cutting both easy and beautiful. 3. We promise to respond quickly and solve your problems within 8 hours！
