The Ant Barrier can be attached to a variety of Food Holders. The only requirement other than it be Plastic, Ceramic, Stainless steel, Wood, or other non porous material, is that it needs to have a 3.5 inch diameter flat surface area on the bottom for secure attachment.
Do not attempt to attach the Ant Barrier to a rounded surface. For example, some pet bowls have flared sides with a rounded inner bowl. Instead of connecting the Ant Barrier to the bowl, connect the Ant Barrier to a plate, platter or tray that has the required flat surface area and then place the food holder with the rounded surface area on top.
