Pregnancy and nursing are responsible for many changes in a cat's lifestyle, as well as in her body. You should pay special attention to your cat’s changing nutritional needs throughout the entire reproduction process.
If you are planning to breed your female cat, it is important to assess her body condition well in advance. Because of the physical demands of pregnancy and nursing, starting off with less-than-ideal health can cause problems.
An underweight cat often can't consume enough food to support her and the developing kittens. Overweight cats may experience abnormal or difficult labor because of large fetuses.
A complete and balanced diet that supports a healthy weight and body condition before breeding helps the female cat maintain her health, and that of her offspring, throughout pregnancy and nursing.
The gestation period for cats is nine weeks. Pregnant cats, like humans, gain weight gradually throughout pregnancy. The energy requirements of pregnant cats are reflected by their weight gain. The energy needs of a pregnant cat should gradually increase so that, by the end of pregnancy, the cat is consuming 25% to 50% more than her normal amount of calories.
Pregnant cats lose weight after giving birth. However, their nutritional needs increase dramatically. Energy needs can be two to three times normal, depending on litter size, in order to produce the milk supply that will support the offspring. Water intake is also important for milk volume.
To ensure a nursing cat is getting enough nutrition, give her a nutrient-dense diet, such as kitten food. Without increasing the amount of food at each meal, increase the number of meals in the day. Free-choice feed her, offering unlimited access to dry food.
By 5 weeks, most kittens show an interest in their mother's food. Gradually, the kittens will begin eating solid food and nursing less. At the same time, the nursing cat will usually start eating less. Most kittens are completely weaned by eight weeks after birth. By this time, the mother's energy requirement is back to normal and she should be eating her usual pre-pregnancy diet.
An upset stomach is more common in cats than you might think. But how can you tell if it's a serious problem?
Every cat owner recognizes the warning signs of an upset feline stomach: the mournful meow, gagging, and heaving retch. But in a flash, the cat seems to snap back to good health while you're left scrubbing the carpet.
The scenario is a familiar one for Cynthia Bowen of Cleveland, Ohio. As the owner of four Maine Coons, Bowen has cleaned her share of messes. 'It would happen every couple of months or so,' she says. 'Otherwise, they were perfectly healthy.'
Although it's not a pleasant subject, vomiting is something cats seem to do almost on cue. Many cat owners accept this as a natural part of owning a pet, but it doesn't have to be that way. Knowing what triggers an upset stomach and what you can do about it will make for a better relationship with your cat.
Repeated cat vomiting should never be ignored because it can lead to dehydration. But, because vomiting is common in cats, how do you know what's normal? 'A general guideline is that if the cat is vomiting one to three times a month, we consider this 'normal,'' says Dr. William Folger, a DVM from Houston.
He considers it serious if the vomiting occurs twice daily for two or three days. If your cat stops eating, seems to have stomach pain, or retches continuously, or if there's blood in the vomit, take her to a veterinarian. And, as always, if you're suspicious that a lingering problem could be harmful to your pet, call your veterinarian. A visit to the office can help relieve your cat's discomfort and your worries as well.
Many owners attribute their cat's vomiting to hairballs, but that's not the only culprit. 'It's careless to assume that most cases of vomiting in cats are due to hairballs,' says Dr. Folger. Two other frequent causes of an upset stomach are:
Eating too fast. Cats sometimes eat too much, too fast. When the stomach wall expands too quickly, a signal is sent to the brain to cause regurgitation. In these cases, the mess on your floor is from regurgitation, not actual vomiting. When a cat regurgitates, he brings up fluid and food from his esophagus by opening his mouth–unlike vomiting, where there's gagging and retching. Regurgitated food is still formed, and may smell fermented. 'Cats that eat too quickly because they are gluttonous or stressed by food bowl competition can regurgitate right after eating,' says Dr. Sara Stephens, a DVM from Montana. But don't assume regurgitation is always a case of eating too fast. It could be caused by esophageal problems, obstruction of the digestive tract, hairballs, or dehydration. If you've forced your cat to eat slowly and he still has problems, contact a veterinarian.
Curiosity. Grass, carpet, and toilet paper are just a few things cats may digest and later vomit. The vomiting is a protective mechanism–nature's way of cleansing your cat’s system. Sometimes, though, curiosity can lead to more serious problems. String, toy parts, and feathers are favorites of playful felines and can lodge in the stomach or intestine, causing repeated vomiting and severe distress. If your cat exhibits these symptoms, take her to a veterinarian immediately; surgery is often necessary to remove the object.
Often, owners accept their pet's vomiting as a natural part of their behavior, but just because cats seem to have more than their fair share of tummy troubles doesn't mean you have to sit idly by.
One simple preventative measure is to get your fast-eating cat to slow down or to simply eat less. Stephens recommends smaller portions, elevating your cat's food dish slightly, or putting an object, such as a ball, into the dish. The cat will be forced to eat around the ball, and thus her intake will be slowed. If you do this, make sure the ball isn't small enough to swallow. And you may need to feed cats in a multiple-cat household at different times and places to reduce competitive eating.
If simple solutions don't work, watch your cat's eating behavior and reactions. Bowen, for example, tried changing her cats' diets. 'Since switching to IAMS®, they rarely throw up,' Bowen says.
'Usually, when you change to a higher-quality diet, there is no problem,' Stephens says. Here are some tips for helping make sure your cat's change is as successful and comfortable as possible:
Go slowly. Make the transition gradually to allow your cat time to adjust. 'Make sure the cat eats something every day,' Stephens advises. 'A cat that quits eating suddenly can develop liver problems.'
Measure up. How much should you feed? Your cat's age, sex, breed, activity level, and overall health need to be taken into consideration. Talk with your veterinarian, then read the manufacturer's recommendations. Premium foods like IAMS cat foods are more nutrient-dense than many non-premium diets, so don't be surprised if the recommended amounts seem low.
Pay attention. Beyond careful measuring, also regularly weigh your cat and adjust the feeding amount accordingly after switching to a premium food. Your cat may appear happy if you overfeed him. But over time, he may become overweight. Tummy troubles can be in the past with your veterinarian’s help and a little effort on your part.
