Answer 2

Here's the simple answer:

How much should my cat eat?

This varies. Average cats may eat between 20-30 calories per pound per day. But note that that is IDEAL pounds. Using 25 calories per day for example, an 8 pound cat could eat 200 calories per day. By the same token, a cat who weighs 20 pounds but should weigh 10 could eat 250 calories per day. You multiply the ideal weight by the calories to arrive at that figure. When working toward weight loss, it's perhaps best to start at the lower end of the scale (20).

How do I find out how many calories are in cat food? See the link "Values in canned food." If it's not listed there, you'd need to contact the manufacturer.....I believe that link provides some help there as well.

And the long answer:

Why do cats get fat? It can be a combination of issues, or just one. First the obvious - overfeeding. This may happen either because you're giving in to the begging or because you're free-feeding (keeping food available all day) and your cat is not self-regulated. The second reason is feeding inappropriate, low-quality food (most dry foods). The third would be medical reasons I'm not qualified to discuss, but they're rare. Most cats are fat simply because they're fed the wrong food and are fed too much.

Is it bad for cats to be overweight? Of course! It's very bad. It often leads to diabetes, not to mention that fat cats probably don't feel very cat-like. Who would when dragging around extra pounds?

Why is dry food bad? With very few exceptions, dry food is not appropriate food for cats. It's chock full of carbs/sugar, doesn't provide enough meat-based protein, and is often loaded with grains such as wheat or corn (which provide those carbs/sugars). Wheat, corn and soy are known allergens and in many cats will cause digestive upsets. Not to mention most also contain "meal" and "byproducts." Cats are obligate carnivores who need to eat a diet high in protein (from meat) and fat and very low in carbs. The mouse is the perfect cat food - meat, organs and bones, with perhaps a tiny bit of grains that may exist in the mouse's stomach. In addition, dry food leaves cats dehydrated. They do not instinctively drink enough water because they're designed to get it IN their food. This results in concentrated urine which can lead to all sorts of problems. And it DOES NOT CLEAN THE TEETH! Really - think about - does dry food clean OUR teeth? If it did wouldn't dentists prescribe cookies instead of brushing?

What should cats eat? Cats should eat a species appropriate diet which very much resembles Atkins (Catkins). A raw diet is the very best, so long as it's properly supplemented to meet a cat's nutritional needs. There are many raw feeding forums available through Yahoo Groups that one can join to learn more. The next best choice is a good quality canned food (or even a commercially prepared raw diet such as Nature's Variety). These foods will have meat listed as the first ingredient, will not contain corn, wheat or soy, may include organ meats, and will not list "meal" or "byproducts." See the What to feed link for suggestions. Additionally, the brand By Nature Organics is a very good food, and at 150 calories per 6oz can, is a very good choice for weight loss.

What about supplements for weight loss? The addition of L-Carnitine to a cat's diet may assist with weight loss. 250-500 mg per day can be added to assist with weight loss. It is probably best to start with a lower dosage until you see how your cat reacts.

How much should my cat lose?  If possible, have your vet set a target weight for you.  But if your cat is obviously obese you don't need to do that before getting started.  In fact, if you're feeding dry food currently it's also a good idea to make the switch as soon as possible, even if only a few pounds need to be lost.  You can also consult this chart to get an idea of how overweight kitty might be:  http://www.placervillevet.com/feline%20b...  

How soon will I see results? Cats need to lose weight slowly, at the rate of no more than 1 pound per month, and often less. This is because rapid weight loss may cause hepatic lipidosis (fatty liver) which can be fatal.

Why is this info different from what my vet told me?  Many vets haven't been properly trained in feline nutrition.  They may attend basic small animal classes, but the only cat-specific training they receive is sponsored by Hills.  Not surprisingly, they are taught to reach for a bag of Hills __/d when a cat presents with a particular problem (k for kidney, d for diabetes, etc.).  I am not a nutritionist but I've gathered this information from people who DO know what they're talking about.  (See links below).

So what should I do?  The solution is to switch the fat cat (and any others in the household as well) to a good quality grainless canned food (or research raw feeding). Because these foods are species appropriate, the cat will lose weight at a safe, slow pace (no more than 1 pound per month). Switching foods needs to occur slowly, and if you're trying to get a kibble junkie to eat canned food, that will happen naturally.

How will I know it's working?  Because this takes time you probably won't "see" any results for quite a while.  You may not even be able to feel them.  If dragging kitty off to a clinic to be weighed once a month is not an option, then you might want to consider buying a baby scale.  The best scale will also list ounces in addition to pounds, so you can really see what's happening.  But if that's not an option, just jump on the human scale yourself and note your weight.  Add cat and repeat.  Then do the math.

That's all there is to it!  Not only will fat cats lose weight, but it and any others in the home will reap many benefits of eating a speciies appropriate diet.

UPDATE: Sophie lost 2 pounds in a year following this plan.  She was already at a healthy weight but the new diet fine tuned her.  Poppy lost 5 pounds the first year which wasn't bad.  The following year when I switched her from canned to raw she gained back a few pounds but that was due to a number of different factors - all of them user error on my part!  But she's almost back down to where she was, and THEN it's only 4 pounds to go!

Answer 3

follow the directions on the bag, it will be different for each food.  or check with her vet..

Answer 4

I usually give mine a little dry food in the morning and 1/3 of a can at night. I never leave food out all day, just water.

Answer 5

Check with your vet.  It depends on the breed and size, even whether it is a male or female.  If the vet put your cat on a diet, he or she would have told you exactly how much to give her.  If you are just putting your cat on a diet because you think she is overweight, then read the directions on the food (whether dry or wet - it's a personal decision - one that has been shown pros and cons of each here many times) or call the toll free number on the label. Your vet can tell you what food is best as well.

Answer 6

Cats are all different, just like humans and other animals.

A large built big boned cat will weigh more than a small boned petite cat.

I have big and tall built cats that are a muscular and healthy 19 pounds... and on the other end of the scale I have a teeny tiny boned cat who weighs in at a meer 7 pounds yet she is very healthy too. Based on their individual body structure I could never compare them.

It's best to assess your cats weight by it's body condition and not compared to other cats.

Here's a chart to help you do that...

www.purina.com/cats/health/BodyConditi...

Once you determine if your cat is overweight, you need to be aware that there is NO such thing as dry "diet" food for cats. Dry foods are filled with carbs that make your cat fat. You can't make a dry food without carbs, so there are no dry diet foods.

The proper amount to feed per cat/per day should be about 5.5 ounces of wet (high quality grain free canned or Raw Meat/Bones/Organ) food.

The calories in that amount of food are sufficient for most "normal" sized cats. Of course a highly energetic cat will need more food to keep it healthy, and a lazy cat will need less food to keep it from getting obese. But 5.5 ounces of wet food per day is a good place to start.

Answer 7

The question is not how much. It is what and what not to feed. Stop feeding dry foods and  start feeding appropriate food for the species and no diet will be needed

Nutrition since there are so many bad things out there is very important to your cat’s health

Contrary to what you may have heard; dry foods are not a great thing to feed a cat.

Please read the label on what you are feeding? What are the ingredients? Do you know what they mean? Is the first ingredient a muscle meat like chicken or is it meal or other things? Learn what meal and other things mean here.

http://www.catinfo.org/#Learn_How_To_Rea...

Dry foods are the number 1 cause of diabetes in cats as well as being a huge contributing factor to kidney disease, obesity, crystals, u.t.i’s and a host of other problems. Food allergies are very common when feeding dry foods. Rashes, scabs behind the tail and on the chin are all symptoms of food allergies probably from the grains. Constipation? Dry food, not enough moisture. Blockages? Again not enough moisture in the food and you are risking something serious. People on this board say feed fiber but this is a cat not a dog and cats are obligate carnivores unlike dogs an they don't eat cereal and don't need fiber.

The problems associated with Dry food is that they are loaded with carbohydrates which many cats (carnivores) cannot process. Also, Most of the moisture a cat needs is suppose to be in the food (Cats are not naturally big drinkers) but in

Dry, 95% of it is zapped out of dry foods in the processing. Another thing, most use horrible ingredients and don't use a muscle meat as the primary ingredient and use vegetable based protein versus animal. Not good for an animal that has to eat meat to survive.

You want to pick a canned food w/o gravy (gravy=carbs) that uses a muscle meat as the first ingredient and doesn't have corn at all or grains  at least in the first 3 ingredients if at all. Fancy feast is a middle grade food as it uses a muscle meat as the first ingrediant. 9lives, friskies whiskas are lower grade canned but still better then dry and wellness and merrick upper grade human quality foods.

Many foods are not mentioned here but if you read the labels you wiull know if it is qualaty. The price offers no guideline.

The optimum food to feed cats has no grains whatsoever, cats have no use for them and many have trouble processing them as well as the carbs. IBD is another disease that is rapidly becoming common amoung cats because of the inappropriate diets being fed.

Also, dry food is not proven to be better for teeth. Does a hard pretzel clean your teeth or do pieces of it get stuck? Why do people constantly repeat this old wives tale and put teeth over the organs like the kidneys?? (I have no clue)   http://www.felinefuture.com/nutrition/bp...
