As a responsible pet owner, you want to ensure that your feline companion is in the best possible health. Your cat health concern is appropriate, because as with any domestic pet, the attachment and companionship is important both to the owner and to the animal. While certain genetic conditions cannot be corrected, general guidelines for nutrition and care will help provide a long and happy life for your cat.
Cats, especially older ones, fall prey to many of the same type of illnesses as do their human companions. This does not necessarily mean that diseases such as diabetes are passed directly from human to cat or vice versa, but cats do get diabetes. They also get irritable bowel syndrome, arthritis and allergies, just to name a few. There are a few exceptions, notably when the owner of the cat is pregnant, but this cat health concern can safely be set aside with just a few reasonable rules.
There is a significant amount of disagreement amongst cat experts as to the correct food for an indoor cat. Much of cat food sales come from presenting cats as being finicky, or needing fresh food, or high protein diets. If you look at the diet of the cat in the wild, you will see that it receives both carbohydrates and protein, since it will eat the entire captured kill. Given that you do not want your cat ingesting wild captured food such as birds or rodents, particularly in your house or apartment, what food comes closest to providing the required nutrients?
Almost any commercial cat food will ease the cat health concern, but some types of preparation will provide added benefits. For instance, if dry food is offered, also provide plenty of fresh water for the cat to drink. Dry food has the advantage of cleaning the teeth which takes care of another cat health concern. Cautions to be aware of include not feeding your cat dog food or human table scraps, as neither one provides balanced nutrition for the cat. Besides, feeding table scraps will create make kitty a nuisance in a very short time.
Foods which do not use dyes are better for cats. Also avoid use of preservatives which can cause liver damage. Finally, even for indoor cats, some grass such as oats or wheat planted for your cat will provide needed nutrients and may help in protecting your other indoor plants.
