This website ranks pretty high whenever I search for questions about cats, but articles often read very AI-like to me. For example:

• https://vetexplainspets.com/can-cats-meow-in-their-sleep/
• https://vetexplainspets.com/what-do-you-call-a-mixed-breed-cat/
• https://vetexplainspets.com/why-is-my-cat-more-affectionate-at-night/

They also often put many quotes from "experts and professionals" in the articles (as can be seen throughout the articles above), yet never name any of them. Also littered throughout the articles are what I believe to be Amazon affiliate links for pet products.

If you'd like, I can make a PR myself if you agree that it is AI-generated.

Please let me know your thoughts.
