Curbing feline obesity by offering smaller more frequent meals

Just as with people, feline obesity is most often linked to excessive food intake or not enough physical activity. Attempts to cut back on calories alone often result in failed weight loss or weight regain in both people and their pets.

So how do you encourage your cat to get more exercise?

Researchers from the University of Illinois interested in finding a method to maintain healthy body weight in cats, looked at a previously suggested claim that increased meal frequency could help to increase overall physical activity.

The idea is to feed cats the appropriate amount of food needed to maintain a healthy body weight, but to offer it in more frequent, smaller meals throughout the day.

Animal sciences researcher Kelly Swanson and his lab at U of I determined that both increasing the frequency of meals fed per day, as well as offering meals that contained added dietary water - "neither method involved decreasing the overall amount of daily food intake - did promote more physical activity among the cats in the study.

"It all comes down to energy in and energy out. It's very simple on paper, but it's not that easy in real life, especially in a household where there is more than one pet. That can be difficult, but I think these two strategies are very practical ideas that people can use," Swanson said.

During the two-part study, the researchers evaluated the activity of the cats between meals using activity collar monitors. In the first experiment, the cats were divided among four rooms and were given dry kibble meals four times per day, two times per day, one time per day, and in the fourth room, were fed a random number of meals per day. The overall amount of food fed to each cat in each room per day was the same; feeding frequency varied.

In the second experiment, the cats were divided among two rooms and were fed twice per day with a 70 percent hydrated diet, using similar amounts of dry kibble used in the first experiment to maintain body weight. Water was added to the kibble an hour before each meal time, Swanson explained.

The cats were placed in their individual cages only during mealtimes so that the researchers could accurately monitor their food intake. During the activity monitoring times, the cats had limited interaction with people.

The researchers evaluated the cats' food anticipatory activity (FAA), which included the activity of each cat two hours before meals were given. During the dry kibble experiment, they noticed that the cats were much more active during those anticipatory times, especially those fed four meals per day and those given meals at random times.

"If they know they are going to get fed, that's when they are really active, if they can anticipate it," Swanson said.

The cats showed an even greater spike in physical activity in the second experiment when they were fed meals with the added water. However, Swanson said the biggest difference in peak activity times with this group occurred in the periods after they had eaten. He added that the researchers had not determined why this was, though factors such as increased use of the litter box, for example, could have come into play.

"I think veterinarians will be interested in this information because it gives them evidence to be able to recommend something to pet owners that could help with feline obesity and diabetes," Swanson said. "When cats are allowed to feed ad libitum, it's difficult to prevent obesity. It is important to identify the right diet. Many owners are accustomed to dumping a pile of food out for multiple cats, just once per day.

"The owner does have an active role in helping with weight management," he added.

Owners often overfeed their cats, assuming that the small amount of food needed isn't going to fill their cat or dog. "Because most pet foods are so digestible and nutrient dense, owners see that small bowl of food and think there's no way they can survive on that but they can," Swanson said.

The key is figuring out how much food is needed to maintain your cat's healthy body weight.

"It is tricky because labels on pet food provide ranges for how much should be fed. If you're feeding a cat, that food is supplied to thousands of cats with different metabolism. Some are spayed or neutered, and ages are different," Swanson explained.

Adding water to dry food, or using wet canned food, may provide a greater gut fill to pets. Swanson also said once the dry kibble absorbs the water, it does look like "more" to the owner, perhaps alleviating the fear that the pet is not eating enough.

He added that rotating between dry kibble meals and wet or canned food could also help in maintaining body weight. Recognizing that the lifestyle of pet owners may not allow for regulating multiple feedings per day, Swanson said if a pet owner could even go from offering only one meal per day to two, it could possibly promote more physical activity.

"With cats, one of the tricky things is that few people can walk their cats. We haven't done studies looking at what happens if you are just in the room with the cat more often and how active you can encourage your cat to be by playing with it. There could be other strategies. From a diet perspective, this is something that is relatively simple," he said.

  1. I think because I let my cats come and go outdoors as they like (I always make sure that where I live is way off the road and out in the country so they have room to safely roam), I've never had a problem with any of them being obese. I always keep dry food in the bowl and then supplement that with a little bit of canned food when they come in in the evenings. The canned food is a reward for coming in when they're called... :)

  2. WE adopted a wonderful cat from rescue once and he died just months later from problems related to his former weight. He was such a sweetie and looked perfect to us but had lost 16 pounds while awaiting a new home. Cats should NEVER be overfed!!!!

  3. I have one cat which is terribly overweight, but really athletic too! We think it is a genetic thing, seeing as his head is really tiny. The vet said it must be such.

  4. We are caregivers to pets and should take as good care of them as possible.

  6. We have had a few fat cats in the past! We have always just left food out and let our cats eat whenever they wanted to but neither of them really over ate as the food lasted them all day...they were just lazy fat cats! lol

  7. It makes sense that if cats don't get a lot of exercise then they would get fat.

  8. It's harder to get cats to exercise so it makes sense to offer them smaller meals so they don't get fat.
