Some people believe that vegan diets for cats cause malnourishment and as a result shorter lifespan.

A 2021 study conducted by the researchers from University of Guelph (Canada) with 874 cats could not confirm shorter lifespan for cats on a vegan diet.

Instead, the researchers found that cats on a vegan diet live just as long as cats fed a meat-based diet.

This research connects nicely with the prior research (see our Blog Post "How Can Cats Be Vegan - Nutrients vs. Ingredients"). The previous studies point to a general conclusion that cats can be vegan on a complete plant-based diet.

The current study builds on this research and takes it one step further, by looking at lifespan of cats.

Veterinarian Dr. Sarah Dodd spearheaded this research and compared 2 groups of cats: cats fed plant-based diets (PB) and meat-based (MB) diets.

“LONGEVITY OF CATS, AS REPORTED BY THE STUDY PARTICIPANTS, DID NOT VARY BETWEEN CATS FED PB OR MB DIETS, AND WAS COMPARABLE TO THE RECOGNIZED LIFESPAN OF DOMESTIC CATS”

The animation below compares the lifespans of 2 groups of cats:

Key slides from the animation:

 

Such lifespan is only possible when cats are fed a complete vegan diet, supplemented with taurine, arachidonic acid, vitamins A, D3 and other nutrients.

The above animation was build based on Kaplan Meier survival function from the study.

And for those considering switching their cat to a vegan diet, the results look very promising.

A similar study for dogs is underway.

It is worth noting that Evolution Diet Maximum Life Non GMO, Evolution Diet Ultra Life Organic, and Evolution Diet Extra Life Organic(canned food) were not fully evaluated in this study.  When these foods are fully evaluated, we hope that study results will show a significant improvement for health and life expectancy using these Plant Protein Vegan - Vegetarian Pet Foods

SAMPLE PACKS

We also recommend trying a sample pack to determine how your cat likes the flavor of the food.

There are several kibble formulas and wet foods to try.
