I washed it once with water, but it's almost new and unused. Feel free to ask any questions or leave comments ☺︎ A cute silicone bowl that combines slow feeding and nose work. This unique pet bowl is designed to encourage pets to sniff and search for their food. It naturally helps them develop the habit of eating slowly. It stimulates their sense of smell and hunting instincts, satisfying both their hunger and playfulness, which helps relieve stress for pets! Eating slowly stimulates the satiety center, preventing overeating and helping to prevent obesity. ★ Many suction cups on the bottom prevent it from sliding during meals. ★ Easy to wash with water and remove dirt. ★ Made of durable, soft silicone that is difficult to break.
