Tabby cats, like all domestic cats, need nutritious meals served twice a day along with plenty of water. Cats require taurine, an amino acid conducive to good health. Taurine is found in animal protein, so a tabby cat's diet must include food containing meat or meat products.
The amount of food each cat needs is based on its activity level. An active pet needs about 20 to 40 percent more food than the maintenance amount specified on the cat food container, and a less active one requires about 10 percent less than the maintenance amount. Cats expend extra energy to keep warm and cool, so their diets may need adjustment during extreme temperatures. A veterinarian's recommendation is the best way to make any temperature-related changes.
All cats require clean water available all day long. Generally, it is best to feed cats twice a day using the portion control method. The portion control method involves dividing the amount of food suggested on the pet food label into two portions. Each portion is given to the cat 8 to 12 hours apart. Finally, treats can be given, but should be limited to no more than 5 percent of the cat's total food intake.
