"for Constipation:
Even though bones are the most natural and optimal source of calcium, one of the most common problems that people encounter in their cats when starting to feed a homemade meat and bones diet is constipation. Constipation may become an issue if too much bone is added but constipation may also result from simply introducing a diet that is very foreign to an intestinal tract that has only dealt with dry food in the past and now needs time to adapt to a new diet, that is, if it can adapt.
Please keep in mind that cats on a homemade diet, such as the one discussed on this webpage, do not pass feces in the same volume, consistency, and frequency that a cat on a dry food diet does.
I have many people write to me with the worry that their cat is "constipated" because they are not passing stool every day. This is not necessarily a sign of constipation. Cats on a low residue diet will often not pass stool every day. There is very little waste contained in this diet and so the volume of feces will be less. Also, the feces of a cat eating the diet discussed below are often dry and crumbly.
Signs of constipation include straining without production of feces, crying in the litter box and acting distressed, as well as excessive licking of the anal area. Defecating outside of the litter box can also be a sign of constipation. These cats often either associate the litter box with pain and develop a litter box aversion or they simply get discouraged and impatient when trying to defecate in the litter box and end up going elsewhere.
When I first started feeding my cats a meat and bones diet over 8 years ago, 2 of my cats did experience a few episodes of minor constipation (cried one time in the litter box but were able to pass the stool within one minute) over the course of the first 2 years. I played around with the psyllium by increasing it, decreasing it, and then finally omitting it. All of my fooling around with the psyllium amount did not seem to make any difference in the moisture content of the stools.
I purchased the guar gum from Whole Foods Market; you can also purchase it online.
There are two types of fiber sources: soluble and insoluble.
Soluble fiber traps water in the stool, thereby softening it, but it does not swell as much as insoluble fiber. It is fermented into compounds that can be helpful for colon health.
Insoluble fiber (e.g., cellulose from vegetables) also traps water but it swells - adding bulk to the stool. However, this is not what we want for cats. Cats are not designed to eat a high plant fiber diet that results in a high volume (large diameter) stool.
Vegetables contain predominantly insoluble fiber making them much less desirable for treating constipation in the cat.
I have been adding 1/8 - 1/4 of a tsp of guar gum to 100 grams (3.5 ounces) of a meal of the recipe on this site + plus an extra ~2 TBS of water. (I am not adding the guar gum to the whole batch of food since I am playing around with the amount.)
There is one drawback to using guar gum....you will no longer be able to brag that your cat's feces do not have any odor. The feces of a cat fed the recipe discussed on this webpage (without guar gum) have very little odor but guar gum is fermented into some pretty stinky gases by the bacteria in the colon.
7/2/11 update: I have been using guar gum for 3 months as noted above and the smell of my cats' feces is not as bad as it was when I first started using it and the gas production has subsided significantly. "
MAYBE THIS WILL HELP OUT???
