Turns a bowl you already own into a slow feeder – It presses into the bottom of your existing bowl and stays put, so you don't buy another bowl.
Match it to your bowl, not your dog – S is 10 cm across and 3 cm tall, for bowls with a 4–6.5" base. M is 12 cm × 4.5 cm, for a 5–7" base. L is 14 cm × 5.5 cm, for anything with a base over 5.5".
Stainless, ceramic or glass – The maker clears all three. Measure the flat part of the bottom, not the rim.
Soft silicone – No hard edges against teeth, and it flexes out again for washing.
Six colors – Purple, grey, orange, black and more.
