It's a silicone mat for dogs I plan to use to place outside under my porch to feed birds. On top of the silicone mat which is nontoxic and waterproof, I will place a nontoxic pet tray on top of that tray there will be 2 small nontoxic bowls of food. The whole point of the mat is when the bird feeds get out of the tray. This easily happens when birds are eating. It's 0.6 high so it should keep the birds seeds inside and also the point of the mat is so birds won't take a crap around that area. They will take a crap on the mat instead of the cement. It won't protect the whole cement but the area of the cement where the food is. Is silicone safe for birds to eat from? The only concern I have is when the bird seeds go on the mat itself and the birds are eating from the silicone. That should be safe since it's nontoxic but what if the birds bite the silicone and eat that by mistake. Is that possible? What the hell. I been searching for a mat for days now and can't find anything better than this. I already have a bird feeder but it doesn't protect the bowl on the bottom from getting wet. A dome doesn't fit there.
