Nutrition
One of the most important considerations when caring for a pet is nutrition. Perhaps the first thing to know is what foods are toxic to your cat.
The huge number of commercial choices can be confusing. How do you decide what's best for your Siberian? More important than whether the food is from a bag or a can is what's in the food, Cats need protein, fat, calories, vitamins and minerals.
​
The AAFCO (Association of American Feed Control Officials) lends its name to packaged foods that they deem "complete and balanced". Foods that display this approval are great choices for your kitten or cat. Without that, you have to analyze the ingredients yourself. They are listed in order of quantity by weight. Since meats contain a lot of water, "meals" may be a better first ingredient, because the protein in them is concentrated. Byproducts may have a bad reputation, but they too are good for your cat. They are not beaks and toenails, but more likely livers, tongues, diaphragms - parts that provide necessary protein and amino acids. In general, adult cats and kittens should have about 38% protein in their diets, at least 9% of that from animal protein. Kittens also need between 12-24% fat. For detailed information, read this article about cats' dietary needs.
Up until about six months of age, kittens need access to lots of protein and calories to support their rapid growth. Offer meals about 6 times a day if you choose not to just leave food available all day (free feeding). Limit feeding table scraps, and make sure that treats are no more than 10% of your cat's diet.
Some foods that are toxic, even deadly, to cats and kittens are:
Chocolate
Caffeine (including coffee grounds)
Grapes (or raisins)
Onions
Garlic
Bones (can splinter and cause internal damage)
Alcohol
Yeast dough
Tobacco products
Xylitol (a sweetener found in some chewing gums and candies)
Raw meat or eggs (risk of salmonella)
Many nuts (see full list of nuts toxic to cats)
Antifreeze (cats like the sweet taste) contains ethylene glycol
​
Dairy products may cause diarrhea or itchy skin.
​
Medications for people can also be dangerous or deadly for cats. Never offer pain, allergy or other human meds to a cat or kitten.

If you are switching your cat's diet, mix the old kibble half and half with the new food for a couple of days to transition them.
