You may have come across articles about whisker fatigue. Whisker fatigue is said to produce stress in cats causing them to paw food onto the floor, fight with other cats, or become apprehensive at mealtime. Some companies are advertising their food bowls as whisker friendly.
I have used all different size bowls over many years with all of my cats. Some were smaller, some were larger. I do not use very tiny bowls for any of my cats or dogs. I believe cats can get their food easier and enjoy a larger bowl without shallow sides most of the time. If any of my cats have a decreased appetite, especially if they are older, I always take them to the practice and do an exam, fecal, blood work, and urinalysis to determine whether there are any medical problems. I would advise all cat owners not to reach for a new bowl as the first line of treatment for poor or no appetite. There are so many diseases that result in a poor appetite. Please keep that in mind before you embrace the bowl theory. Cats that eat poorly or not at all will develop fatty liver disease as early as 72 hours after they stop eating. Cats with Kidney insufficiency, fever, diabetes, Inflammatory Bowel Disease, cancer, FIP, feline leukemia, FIV, or intestinal foreign bodies will stop eating.
I have used elevated feeding bowels for my older dogs and cats who may have cervical (neck) arthritis, and believe that is a good idea.
