Your once green and perfect lawn is now starting to have dead patches and you’re probably wondering to yourself why. There are many reasons for dead grass, but the culprit could be right in your living room without you even knowing.
You are now left wondering, does cat urine kill grass? The answer to this question is yes. Large amounts of cat urine will burn your grass which will result in a brown patch. Cat urine actually acts like a fertilizer to grass which means in small amounts it can be beneficial.
This is not always the case if a cat pees a very large amount in one area of your grass. This is what will cause the brown patch to appear. It is possible that overtime the grass may grow back, but in most cases you will need to replant grass in the damaged area.
Why Does Cat Urine Kill Grass?
The reason why cat urine kills grass is simply because of the nitrogen content in cat urine. Cat’s consume a good amount of protein in their diets. The way their body breaks down part of the protein is by the removal of excess nitrogen by the kidneys. Anything filtered through the kidneys is excreted in the form of urine.
Urine, unlike feces, is absorbed instantly in the grass which will then in turn kill the grass. This is the main reason fertilizer is feces based because it is absorbed at a much tolerable rate. This is also why small amounts of urine will not kill or damage your grass, but will actually help it with similar effects to fertilizer.
