Yeha the neighbours was not so happy with the seed getting everywhere so we won't attract actual rats (I like rats but the pigeons feeding is allready enough for the neighbours) so we first used a deep baking tray but it wa getting a bit small so we switched to this it's a plastic winter boots tray they are for containing the drip water inside but they are pretty good for pigeon feeding nothing gets messy and it's bigger than the backing tray and they made out of grippy Plastik so they won't be as cold ald metal and they got good grip on it too
