As any cat keeper knows, cats can be very fussy eaters. One day they may love their food, and the next, they may turn their noses up at it thoroughly.

Cats usually need around 20 calories per kilogram of body weight each day. For a 4kg cat, this equates to about 80 calories per day. In any case, each feline is unique, and some might require pretty much than this.The average adult cat should eat around 190 calories per day. If your cat is eating less than this, it may be at risk of becoming malnourished. Malnourishment in cats can lead to several health problems, such as weight loss, muscle wasting, weakness, and lethargy. In severe cases, it could be perilous.
