Nothing slips - the Wolters Rainbow bowl mat. Food bowls for dogs and cats stand particularly well on the Wolters Rainbow bowl mat. It is made of natural rubber, naturally coloured and therefore absolutely safe for pets. A practical overflow edge protects the floor and a nub-like structure prevents the bowls from slipping. The pad can also be rolled up, making it the perfect companion when travelling. The bowl mat can be wiped clean with a damp cloth.
