Cats: Ethics

Last show’s investigation of whether cats can be vegan leaves us with an ethical quandary. What should vegans feed cats?

Erin and I reflect on listener’s comments. The three expert veterinarians examine the moral issues. And I ask Eric Weisman, CEO of major US vegan cat food brand Evolution, some tough questions.

Veterinarian Guests

There is more information about Lorelei Wakefield, Andrew Knight, and Jean Hofve on the episode page for the last episode, “Cats: Can They Be Vegan?”.

Since then, Lorelei Wakefield’s site, vegetariancats.com, has returned, and there’s lots of information there. She is also conducting a new study, with a focus on the urinary tract issues we discussed in the last show, and is asking cat owners to complete her survey and share medical records.

Erin “Red” Grayson

Erin can be found at Tumblr (currently)ErinRed.com (under construction), and @ErinRed on Twitter.

She mentions a discussion about the ethical dilemma of vegan cats with Prof Gary Francione in a February 2012 episode of Red Radio, and quotes Hamlet.

Lisa Freeman’s 2004 Study of Cat Foods

Lisa Freeman was the senior member of a team that tested:

  • Vegecat KibbleMix, from Harbingers of a New Age
  • Evolution diet vegan gourmet vegetable stew entrée, Evolution Diet

(Technically, I should be calling it the Gray study, as she is the primary author.)

In our brief conversation, Dr Freeman strongly backed the veterinary consensus, saying there was no safe way to feed a cat vegan.

The study is:

Eric Weisman and Evolution Diet

Eric Weisman is the Chief Executive of Evolution Diet, manufacturers of vegan foods for cats, dogs, and ferrets, in St. Paul, Minnesota USA. He also posts at WeismanNutrition.com.

Loss of Chiropractic Licence

Eric Weisman gained his licence in 1979, but in 1982, he was reprimanded and put on probation for one year; and again in 1986 and 1987. The complaints process ended in a 1997 Order in which Mr Weisman agreed that he’d committed a number of practices, including:

Advertisements in connection with Respondent’s [Mr Weisman's] pet food business which identify Respondent only as “Dr. Eric Weisman” and from which a reader could reasonably infer that Respondent is a veterinarian instead of a chiropractor.

He accepted a penalty of 300 hours of community service, a $15,000 fine, and some ethics courses. In 1999, the board found he had paid the penalty in time or money; and in 2002 the board revoked his licence for breaches of the 1997 order [PDF] , including:

Engaged in advertising that is false or misleading

The memo that the board attached to the order said that:

The advertisements admittedly issued by the Respondent also include claims that his treatment programs for animal and human disease have “good long-term results in most cases.” During his January 9, 2001, conference with the Panel, the Respondent stated that he defines a “good long-term result” as an instance in which an animal using his products and/or treatment programs survived longer than was originally predicted by a veterinarian. Because the Respondent’s definition of “long-term is contrary to its common dictionary definition,” his claims about “good long-term results” also are false and misleading.

The Respondent has disseminated advertisements in which he claims his research or the research conducted by his pet food company proves dogs and cats can  live 20-25 healthy years and thereby implies that the use of his products lengthens the life expectancies of animals. He admitted, however, that he does not have a dog that has lived 25 years, he did not conduct any actual research other than calling about 30 veterinarians, and he was not referencing animals that had used his products, the Respondent admitted  during his conference with the Complaint Panel that this claim is “just an assumption” on his part because he distributes the food throughout the United States. This claim is false or misleading because the Respondent has no actual data or information to support this representation. His claims about animals’ life expectancies, therefore, are false or misleading.

Thus, “overselling”.

The Minnesota Court of Appeals upheld the revocation the following year.

Those documents, again, are:

Court Action

The Minnesota Board of Veterinary Medicine sued Weisman in 2002; the parties settled the case in 2003 by agreeing an injunction [PDF].

This banned him from, in part:

Engaging in any conduct that constitutes the practice of veterinary medicine …

… making any claim that Defendant’s pet food or other products for animals will treat, prevent, or otherwise affect a disease or condition … unless Defendant has first obtained written authorization from the Food and Drug Administration …

Directly or indirectly representing or implying, in connection with the sale of pet food or any other product or service, that he or any business in which he has an ownership interest has conducted “research,” including, but not limited to, “clinical trials,” “human studies,” “case studies” or “literary research,” that supports claims about the efficacy of the pet food, product or service.

Directly or indirectly representing or implying that that (sic) any animal’s life will improve through the use of Defendant’s pet food or other products …

In 2011, the Ramsey County Sheriff’s Office brought 58 charges of practicing medicine – on humans and other animals – against Weisman [PDF]. But in February 2012 all of these were dismissed bar three charges of contempt of court [PDF]  – to which Weisman plead guilty.

Local media covered the case:

He has also been criticised by blogger SkeptVet.

Ida Fong on Animal Voices podcast and Dan Robinson who runs the Vegan Cat Institute website both offer strong anecdotal criticism; whereas the majority of Amazon reviews offer positive anecdotes.

    Dear Ian,

    ( vegan cats,an interesting topic).

    I would like to make a comment. I believe people ( especially those of us on a vegan diet and on the vegan lifestyle journey) should be discouraged from keeping cats. (especially from getting a cat ,when already taking the vegan journey). The same could be said for dogs unless rescued and encouraged to eat a vegan diet.

    Regards,
    Simon.

  2. Lorelei Wakefield says :

    Ian,

    Thank you for all the research and lead-following you did. To clarify some things:
    - I believe at one point you stated that all the cats in the blood test portion of my study were on Evolution Diet. Actually, it was mixed among Evolution, Vegecat, both, and some were fed additional human vegan food.
    - There is also talk about pet food being a by-product of the meat industry. While this is true in some brands, many of the higher quality pet food brands use higher quality cuts of meat. This means that animals are being slaughtered specifically for that pet food.
    - Regarding ethics, I know my second argument may sound silly but I explain in much more detail in this 3 part essay

    - While I mention potential sources for error in Dr. Freeman’s study, that doesn’t mean that I don’t believe her results. Those factors were pointed out in the study itself. The research was very important and we should take heed. I’m merely saying there’s a possibility that the samples tested were not representative samples. And as you point out, since then VegePet realized an error and took action to correct and improve their quality assurance.
    - I listened with great interest to your interview with Eric Weisman of Evolution. I just want to mention that there are also other vegan cat food companies such as VegePet (James Peden) run by caring and trustworthy individuals.

    While producing perfectly objective journalism is near impossible, I think it is wonderful that you tried to present a balanced argument. Thank you so much for giving this subject your attention.

    • Ian McDonald says :

      Dear Lorelei,

      Thanks for your gracious comment. It was really good to have your expertise in the show, and I’m sorry if you feel some bits were skimmed over.

      To take each point in turn:

      What were the cats in the study eating?

      Thank you for noticing and correcting this. The error crept in during a redraft.

      That statement is even followed by a clip of you talking about the study that makes it clear that some cats were on Vegecat. When I next set up the studio, I’ll replace my cue.

      I regret the error.

      Pet food: a by-product?

      I think that Erin and Jean both make similar points.

      Cats with a conscience

      I’m not sure if you wish it was dealt with differently, but in half an hour, not every sub-topic can be dwelt on and explored.

      Your philosophy on what a cat with a conscience would do was heard, challenged, and we moved on (although I think most of what you said to me about the subject made it into the show).

      Limitations of Lisa Freeman’s study

      If Dr. Freeman had granted an interview, I would have used audio of her describing her own study instead, because it’s better to have a scientist describe their own work if possible.

      When writing a sript, it’s perhaps too easy to pull together the sides of a case by saying “On the one hand X, on the other hand Y”. Particularly if different people are stating the different sides, it’s easy to accidentally make the discussion sound more polarised than it really is.

      I’ll pay more attention to that.

      Other vegan cat foods are available

      Apart from Evolution, I didn’t mention vegan cat food brands unless they came up naturally in the story – which they did, several times. I didn’t go out of my way to list brands because I try to make this show for a global audience, and not all cat foods are available everywhere. Evolution, for example, isn’t available where I live in London.

      I was tempted to say “Other vegan cat foods are available” after the Evolution segment, but I thought it was too much of a barbed comment, and a bit of a Brits-only joke.

  3. Jane Easton says :

    Jed Gillen’s excellent book ‘Obligate Carnivore’ (he got advice from veterinarians and scientists) explains that 1. artificial taurine is added to meaty commercial cat food – so presumably it doesn’t contain enough! and 2. modern veg*n cat foods contain taurine and a good balance of other nutrients to replace meat. The main thing is whether the cat will take to it! Young cats may do, others will do their feline sneer and refuse it, but it’s got to be worth a try. Dogs are more likely to take to it and do very well indeed tho I also know of some cats. I’d advise anyone interested in this issue to read Gillen’s book – he makes some interesting points, such as harm-reduction – ie it might be possible to feed a proportion of a cat or dog’s food vegan even if they don’t take to it entirely. As to ‘natural’, well, I’d argue that we have too many humans and also domestic animals on the planet; not a particularly natural situation! Each uses up massive resources and their meat consumption causes endless suffering to animals and the environment.

  4. MarkGYo says :

    Here’s a simple and easy choice for you. If you don’t want to feed your dog or cat a biologically appropriate diet then don’t adopt a dog or a cat. Both are biologically Carnivores. No, a dog is not an omnivore as you’ve been told. Scientifically and Biologically it is classified as a carnivore for a reason. It’s teeth, inability to manufacture amylase in the saliva, high acid pH, and mouth full of sharp teeth all prove this is a true carnivore. Want to see a true omnivore? Go visit a bear in the wild. The dog will eat some plant material in the wild because it receives amylase from the prey it kills. Therefore, amylase is no issue. However, dogs fed a standard, crappy, dog diet receive no amylase and are force to create this amino in their pancreas: which puts an incredible strain out their bodies. This information is freely available but most of my vegan friends do not wish to come to terms with this. The reason is simple. Dog food companies are continuing to lie to people and call them omnivores? Why? Look at the filler in almost every dog food. What is it? Corn or Wheat, which are both highly, indigestible grains. Again, this is because dogs do not produce amylase at the point of entry to help them break down plant matter. This means the grains go down slowly and literally ferment while the pancreas creates an emergency supply to digest the food. We, as herbivores, do not have this problem. So, if you don’t want to feed your dog meat, don’t get a dog. They don’t thrive on a plant-based diet. Therein, is the lie. They only survive.
