I have to say the girls have been on it for nearly 2 weeks and ALL,yes all, the scratching has gone! The poohs still have a bit of a way to go but thats probably down to the amount and adjusting it to the prefect amount I've no doubt will take time. I even supported the local family pet shop which I have to say are possibly the best pet shop in the world. They take time to sort you out, don't rush or pressurise you and they all love the dogs that come in. I won't mention the name but anyone in peterborough should check them out. Well I hope other Nutro feeders are having the same great results as we are.
