Did you actually read the article? Cause I did and here are some highlights from the article regarding felines specifically:
Sample sizes are tiny
3.2. Feline Studies-Meta-analysis was considered if more than one study presented the same outcome data. However, meta-analyses of these data were not possible due to (1) differences or lack of a comparison group, e.g., a meat-based diet comparator or (2) no presentation of a measure of central tendency or dispersion to input into the model.
Hypokalemia is: a low level of potassium (K+) in the blood serum.[1] Mild low potassium does not typically cause symptoms.[3] Symptoms may include feeling tired, leg cramps, weakness, and constipation.[1] Low potassium also increases the risk of an abnormal heart rhythm, which is often too slow and can cause cardiac arrest
3.2.1. Hematology/Biochemistry-Only three studies [27,29,30] have carried out hematological and/or biochemical analysis of blood in cats that were fed vegetarian diets, and it is worth noting that sample sizes were low. Cats on a high-protein vegetarian diet exhibited hypokalemia which accompanied recurrent polymyopathy [29]. There was also increased creatinine kinase activity, likely reflecting the muscle damage caused by the myopathy, and reduced urinary potassium concentrations.
Myopathy is: a disease of the muscle[1] in which the muscle fibers do not function properly.
3.2.3. Clinical Findings-In cats fed vegetarian diets that were supplemented with potassium, a myopathy was seen within 2 weeks of the dietary change [29]. This was characterized by ventroflexion of the head and the neck. The cats also showed lateral head resting, a stiff gait, muscular weakness, unsteadiness, and the occasional tremor of the head and pinnae… Weight loss and poor coat condition have also been observed in cats fed vegetarian diets [29,30]. However, most cats in another study had a normal coat condition and no obviously diet-related clinical abnormalities picked up by clinical examination [27]. Clinical signs of lethargy with altered mentation, dysorexia, and muscle wasting, along with gut signs of bloating and increased borborygmi have also been observed [30].
These are guardian based reports which means there is significant bias from the owner to report positive effects and look over the negatives
3.2.4. Guardian-Reported Health Effects-Guardians generally believed that the transition to a meat-free diet had been positive. These studies are valuable, as large sample sizes of respondents (animals) are generally employed. Some guardians did notice an increase in stool volume but noted no issues with consistency [27]. When considering other aspects, coat condition was shinier [27], there was an improved scent of their animals (particularly relating to breath odor) [27], there was a tendency to be at the ideal body condition score rather than being obese [28,31].
This is about as close as you can get to justifying it , IF you fixate on ONE aspect and ignore everything else in the journal article:
Dodd et al. (2021) [31] collected dietary information for 1026 cats, of whom 187 were fed vegan diets. The latter were more frequently reported by guardians to be in very good health. They had more ideal body condition scores and were less likely to suffer from gastrointestinal and hepatic disorders than cats that were fed meat. No health disorders were found to be more likely in cats that were fed vegan diets. The reported differences were statistically significant.
So please explain to me how myopathy setting in and causing tremors after only two weeks of transitioning to a non meat based diet is good for cats?
So for the record you are dead flat wrong by your own damn source because you didn’t read it or you ignored all the bad parts.
Happy to see someone who read through the analysis! I just looked back at your criticism and you make stone goods points. I did notice that almost all the negative effects are coming from the same citation in the study, so I looked into the study they are citing there. Here’s a link to the PDF of that study.
The main take away for me from this study is that they were feeding the cats a “vegetarian human diet,” specifically casserole mince along with a couple others. Feeding these cats a diet designed for humans is obviously bad, but it doesn’t speak to commercial food designed for cats. You can use this to say that a homemade vegan diet is not good for cats. I’ve always said, don’t do a homemade diet for your pets.
There were also negative outcomes from citation 30, but the full text is behind a paywall, so I can’t really check on it. Of anyone has a copy I’d love to read it.
The studies that did use commercially available cat foods (literally all the other studies linked) found that the cats fed a vegan diet were within the range for regular healthy cats.
I am not making the claim that vegan diet is healthier. I am not claiming that you can make your own cat food at home. My specific claim is that there is not a statistically significant difference in the health of cats that eat commercially available vegan cat food. If you have a similar quality study to the contrary, please post it. Until that happens, I’m going to stick with the researchers who published the study, when they say:
Perhaps a take-home message is that use of commercially prepared vegan pet foods appear to be safe for use in cats and dogs but further research is needed.
I noticed you forgot to include a very important contextual sentence for your myopathy quote:
Only three studies [27,29,30] have carried out hematological and/or biochemical analysis of blood in cats that were fed vegetarian diets, and it is worth noting that sample sizes were low. Cats on a high-protein vegetarian diet exhibited hypokalemia which accompanied recurrent polymyopathy [29]. There was also increased creatinine kinase activity, likely reflecting the muscle damage caused by the myopathy, and reduced urinary potassium concentrations. Potassium supplementation prevented development of this myopathy, strongly suggesting a link between the potassium and myopathy.
Meaning there was a health problem when one of the cats’ dietary needs wasn’t being met, which no longer appeared when the deficiency was corrected.
Even so, no one was trying to claim every conceivable vegan food mix is healthy for a cat. Of course trying to switch an animal who would be a carnivore in nature to a healthy synthetic vegan diet would be difficult. But there only needs to be one diet that succeeds to show it’s possible. And unless you’re going to claim literally all of the vegan cat guardians who reported healthy cats are lying about their cat’s health or diet, that requirement has been met.
