How does giardia affect cats?

As a result of the malabsorbtion caused by the presence of the parasite in the intestine, cats infected with Giardia do not absorb the right amount of nutrients, even though they are fed the right amount of food.

In kittens and cats with poor immune systems, in which the Giardiasis also causes severe diarrhea, the weight loss is very easy to notice because they lose a large amount of weight in a short period of time. In older cats with strong immune systems, on the other hand, the weight loss may not be so easy to notice because it happens over a longer period of time.

In kittens and cats that come into contact with Giardia for the first time, the diarrhea is acute, but its evolution can be continuous or intermittent. In older cats, with strong immune systems, the diarrhea can be limited to a softening of the stool, which is usually not noticed.
