We have had continuing issues with Wainwrights Variety trays mature, blowing and rotten food inside the boxes. We have had three purchases of these boxes and every time there is an issue with food having gone off because the tray has blown, on one occasion three boxes were affected. Pets at home apart from one response giving us a complaint no. 1210461 will not respond to our emails - now standing at three! Reviews I have since read suggest this problem has been going on for several years, and yet Pets At Home apparently don't care if their food makes our dogs ill! Trading standards now been informed. In future I will not be buying any food from this store, they don't care and can't be trusted!
