    Vegan versus meat-based cat food: Guardian-reported health outcomes in 1,369 cats, after controlling for feline demographic factors [Andrew Knight, Alexander Bauer, Hazel Brown | Published: September 13, 2023][1]

    Abstract

    Increasing concerns about environmental sustainability, farmed animal welfare and competition for traditional protein sources, are driving considerable development of alternative pet foods. These include raw meat diets, in vitro meat products, and diets based on novel protein sources including terrestrial plants, insects, yeast, fungi and potentially seaweed. To study health outcomes in cats fed vegan diets compared to those fed meat, we surveyed 1,418 cat guardians, asking about one cat living with them, for at least one year. Among 1,380 respondents involved in cat diet decision-making, health and nutrition was the factor considered most important. 1,369 respondents provided information relating to a single cat fed a meat-based (1,242–91%) or vegan (127–9%) diet for at least a year. We examined seven general indicators of illness. After controlling for age, sex, neutering status and primary location via regression models, the following risk reductions were associated with a vegan diet for average cats: increased veterinary visits– 7.3% reduction, medication use– 14.9% reduction, progression onto therapeutic diet– 54.7% reduction, reported veterinary assessment of being unwell– 3.6% reduction, reported veterinary assessment of more severe illness– 7.6% reduction, guardian opinion of more severe illness– 22.8% reduction. Additionally, the number of health disorders per unwell cat decreased by 15.5%. No reductions were statistically significant. We also examined the prevalence of 22 specific health disorders, using reported veterinary assessments. Forty two percent of cats fed meat, and 37% of those fed vegan diets suffered from at least one disorder. Of these 22 disorders, 15 were most common in cats fed meat, and seven in cats fed vegan diets. Only one difference was statistically significant. Considering these results overall, cats fed vegan diets tended to be healthier than cats fed meat-based diets. This trend was clear and consistent. These results largely concur with previous, similar studies.

    Geerling also demonstrated that the 2GB Pi 5 comes with a couple of unexpected benefits that Upton didn’t mention in his announcement—that the 2GB Pi 5 runs a little cooler and uses a little less power than the 4GB and 8GB editions. The 2GB Pi used just 2.4 W or power at idle and 8.9 W during a CPU stress test, compared to 3.3 W and 9.8 W in the 4GB version. The SoC of the 2GB Pi measured 30° Celsius at idle and 59° under load, compared to 32° and 63° for the 2GB version. Those are all small but significant differences, given that nothing has changed other than the SoC.

    As to the exact functionality that was removed from the chip for the 2GB version of the Pi, the company hasn’t gotten specific. But Geerling speculates that it’s mostly related to functionality that’s being handled by the custom RP1 I/O chip—RP1 handles the Ethernet and USB controllers, display interfaces, and GPIO, among other things.


    So is it worth stepping down to a 2 GB Pi 5 just to get the simpler D0 chip? No. But is it cool to have a cheaper 2 gig option exist? Yes. Just make sure you have a use case for it that doesn’t need a ton of RAM.[1]
