Likely Causes There are several likely causes for constant diarrhea in pets.

Bugs and Lizards Cats and Dogs love to stalk. Some bugs have built-in toxic defense glands; others are toxic because of exposure to pesticides.

Hairballs pose a potential danger by blocking the passage of digested food through the intestines, causing an impaction.

Since hair is not easily digested, it can compact with undigested food in the stomach and gastrointestinal tract. Compactions can cause painful constipation.

Commercial Pet Food is another likely suspect. Open bags of dry food or canned food left out too long are potential breeding grounds for bacteria. They also attract bugs, and mice that leave droppings, as well as eggs that get eaten by your pets.

Household Cleaning Agents Your pets spend most of their lives close to the floor. They breathe in toxic agents and lick their paws, consuming them. Toxic agents are a cause of skin problems.

Premature Weaning can weaken your pet’s immune system for life. Kittens and Puppies need a full term of mothers milk in order to develop strong immune systems. Premature Weaning is an overlooked cause, and the likely cause of many cats now being lacto-intolerant.

Health of Mother A healthy mother is far more likely to produce healthy offspring. She should be well cared for before, during, and throughout weaning.
