Made of non-toxic, safe and ecological material. They are easy to clean and assemble in seconds! Support included: you may not know it, but with your cat eating at a high position is something good for them. It helps digestion because it opens their air flow. Tilted: the bowls rest on a slope so that the kitty food falls towards them. Their whiskers will not touch and they will have easier access to their meals. Non-slip: the support is non-slip and resistant to spikes, so everything stays where it is needed.
