cats are more than intelligent

My family owns a cat shelter, and in our experience, cats are more than intelligent. While it may be true that whomever started this article wasn't truly concerned about the topic, just being difficult, they may have inadvertently had a point. In order to ensure that the neutrality and accuracy of this article is in full effect, it may be wise to have examples of perhaps studies or personal experiences with cats to ensure anyone biased against or for felines understands the entirety of the cat-mind complexity.

For example, we have known foster cats and stay-at-home cats we have had have learned from each other. Our stay-at-home cats 'taught' the fosters how to open cabinets and drawers that didn't have any handles, and the foster cat 'taught' our stay-at-home cats how do jump from our second story to a perch on the first floor. While it seems a strange example, the fact that they discovered these feats, when human children have difficulty with them, and the fact that they 'learned' from each other, despite being an asocial species, seems like moer than intelligence to me. It seems almost like an inexperienced hive mind to me. Anyway, please let me know what you think, thank you so much!
