Knock numbers, also known as octane ratings, are a measure of a fuel's resistance to engine knocking or pinging. Engine knocking occurs when the air-fuel mixture in the combustion chamber ignites prematurely, causing a knocking sound and potentially damaging the engine. The higher the knock number, the greater the fuel's resistance to knocking. In general, higher performance engines require fuels with higher knock numbers to prevent knocking and optimize performance. **

Cats may knock over their food and water dishes for a few reasons. One possibility is that they are trying to play with their food or water, as cats are known for their playful nature. Another reason could be that they are trying to get your attention, especially if they are not happy with the type of food or water you are providing. Additionally, cats have a natural instinct to hunt and forage for their food, so knocking over their dishes may be a way for them to simulate this behavior. It's important to observe your cat's behavior and make sure they have a stable and secure feeding area to prevent this behavior. **
