Every cat needs nutritious food, but watch out. Far too many cat owners equate food with love and wind up overfeeding their cats. Just as humans who eat all day long risk getting obese, so can cats get overweight if you constantly feed them all the time.
When going out of town, make sure you put out plenty of food for your cat, but make sure your cat doesn’t gobble all the extra food down in one sitting. If your cat wolfs down any food it sees, you might want to get an automatic feeder.
When you consider all the different ways your cat could become unhealthy by overeating or not eating enough, you’ll realize you need to spend most of your time keeping your cat happy rather than focusing on yourself.
