I had to buy a taller tree as my new dog would drink and eat from our cats bowls. We had a 3 tier tree but opted for this 4 tier tree and it works perfectly. It has kept our dog from the cat’s water and food bowls. I placed her bowls with wet and dry food on the top tier and her circulating water dish on the second highest tier. Quality seems fine and it’ll last a while. We had our prior tree for almost 4 years.
