Most of the health benefits reported for this group also did not reach statistical significance, which may be the result of simply not having enough animals in the study.
The authors reported a tendency towards positive effects of vegan diets. This means there was a general trend (which was sometimes strong), but doesn’t necessarily mean there is a very predictable relationship.
As a survey study, it’s not possible to confirm exactly what the cats were eating. Many of them went outside and may have hunted down meaty treats even while on a vegan diet. Some owners also fed their cats treats and essential nutrient supplements, so any beneficial effects (or a lack of harmful effects) may not be due to diet alone.
Another missing piece of information is how long the cats were kept on the diet. We might assume one year – but this isn’t specifically stated. This is important information since deficiency diseases can take time to develop.
Finally, any study assessing animal health will have inherent limitations if it’s designed as a survey. Pet owners usually aren’t medically trained and their “opinions” can be subjective and therefore biased.
Owners who had removed or reduced meat in their own diet were over-represented in the study. These people may already anticipate vegan diets are better for health, and this thinking could influence their responses.
It’s also worth noting the study was funded by ProVeg International – a food awareness organisation that promotes plant-based products. While this might not have impacted the validity of data, it could have influenced the stance taken when reporting on the results.
