Yeah, Sea Lions are obnoxious and destructive but not usually malicious. But Seals can be mean just for fun. They would make excellent early 2000s prank show hosts.
Fun fact, trying to determine if a dog is more intelligent than a cat is nearly impossible because that it's hard to tell if the cat doesn't understand the test or just can't be bothered.
The cat understand perfectly the test, but think that, if you like it so much, leave me alone and do it yourself. A dog is a pack animal and for this reason it obeys, yes or yes, the leader of the pack, the owner, a cat or felines in general, with the exception of lions, they are solitary hunters and do not have the concept of a leader, A cat sees you as an equal, at most a friend, but not as a leader. This has nothing to do with intelligence, but with the very nature of these animals.
It depends. If the toddler is trying to actively kill themselves, they are super smart AND fast. On the other hand, I'm told that some cats share a braincell, and if it's not their turn with it, then that's that.
