With respect to feeding directions, due to label space limitations it can be confusing as to how much to feed certain ages of kittens. Remember that the feeding directions on the package are just guidelines and your cat may be different. A good rule of thumb for a growing kitten is to provide food throughout the entire day. You may have to adjust the amount of food provided each day, but most cat owners usually fill a bowl in the morning and come back later in the day/evening and add more. Cats tend to be nibblers meaning they normally eat many small meals throughout the day. Since you have a fast growing kitten it is very important during this stage of life that your kitten has access to all the nutrition he needs. Also since many growing kittens can be very active and playful, the more energy available to the kitten the better. It is still very important that you keep an eye on your two cats' body condition if you change the amount of food offered. If your kitten begins to gain too much weight, you will want to adjust the amount offered so your kitten gains at a healthy rate and doesn't become obese.
