The benefits of correlating Perception with Intelligence outweigh the vestige of weirdly and inaccurately "wise animals". (For example, humans are apes, and it feels off to quantify other apes as if more perceptive than humans on average, nevermind wiser or with more willpower. Also, humans have among the best senses of vision of any reallife animal species. Our senses of hearing and smell can be less good comparatively.) Most animals have very poor observation skills.
Certain reallife animals have "superpowers", relative to humans, and it is fun to call attention to these. Sometimes, the senses of a particular animal are flavorful, and like a magic spell description, it is a judgment call whether to detail or abbreviate them in a statblock. The Cat is likely to be a familiar for the character of a player who is an animal lover, so maybe a bit more flavor is worthwhile.
So for example, a Cat can use Feline Senses to perceive a nearby creature or something new, but cannot use it to recognize a secret door or trap (tho the cat might smell a poison).
Feline Senses have the following in mind. A cat has superhuman hearing, even superior to canine hearing. In absolute darkness, a cat can still hunt prey by sound, and when reaching 3 feet away can pinpoint a location within inches. Surprisingly, the cat knows the size of the prey by its sounds. Plausible anecdotes have cats hear a heartbeat or breathing "from across a room". It is thinkable to give the D&D Cat something comparable to Tremorsense, but this would be a big deal in the game. As is, Feline Senses can sense the presence of nearby Invisible creatures. Cats can hear frequencies beyond human and canine hearing, and sounds from further distances away, but I doubt this matters in most gaming situations.
The cat is famous for its night vision, but its day vision seems roughly the same as humans. Apparently, cats have difficulty seeing in the distance. The clearest sight is about 20 feet, and after that things gradually get blurry. Cats lack facial recognition and rely on smell to identify individuals. Shades of red look greenish or grayish.
Probably the D&D Cat hit points should be higher. Cats are surprising tough for their size. I am unsure how to reconcile low hit points with surviving Falling damage. Maybe the distance of a Long Jump is normally subtracted from the distance fallen, especially when intentionally jumping down from a height?
