Hi! How would you draw a tool-evolved cat paw?

Aeons ago I wrote some speculative biology thoughts on what a tool-focused cat would begin to look like, and mentioned the way that a caw's paw might evolve. I can try to draw it out as a sketch; but fair warning that I put my art style points into cartoony anime stuff SO you're not gonna get a realistic drawing lmao

Evolution doesn't "think." It's many changes over generations that snowball into bigger ones. So I tried to look at WHAT exactly is happening between an animal with less sophisticated tool use (chimp) and one that COMPLETELY relies on tools (human) to predict where the cat's paw would end up in a few thousand generations.

Please note! My paw would still be a "link" between the ancestor, and something even more reliant on tool use. This proposed species would still be 100% capable of doing what the cats in-canon do, like hunt alone. It's for a feline species that is tool-ADAPTED, not tool-RELIANT.

(In that way, it's more comparable to, say, a lemur and a chimp. But lemur palm refs were hard to find and I did this quick because I've already thought about it.)

This paw would exist in-tandem with a "tool tooth;" A V-shaped gap in the jawline that a single fang would nestle into. Early tool-using felines would likely use their mouth to "break" or "shear" their crafts, leading to broken teeth that would make them less successful. So there would be a lot of evolutionary pressure to have better, stronger teeth.

Evolution doesn't do "one thing at a time," so if you happened to port yourself into a group of these cats and watch them craft stuff, you'd see them using their mouths as well as their paws!

Finger Size + Tool Claw

When you see real cats batting stuff around and manipulating things, and when you look at canon where they like to "hook things on a claw," it's usually the index "finger" they favor. In fact, they do a LOT of "poking," even when a cat bats at something they seem to mostly explore with the tip of their paw.

So I figure that would actually be a big difference between this species and humans.

Unlike us, who usually have our middle finger as the longest (though there are exceptions) so we can "stabilize" the things we grab, I'd give these guys a "Tool Claw" which is not involved in grappling at all. It's longer, more deeply grooved, but also more fragile than the "hunting" claws.

When at rest, the Tool Claw would stick out from the rest of the foot, straight upwards. The fur is able to "sheathe" the other three, but the index's would be too long to be fully hidden.

Because one of those fingers is now mostly taken out of combat, the pinkie would probably thicken up to compensate. Another difference from the human hand. I can imagine that if the trend continues, they might end up supporting their full frontal weight on the pinkie pad to free up the other fingers for tool use.

(But evolution's not always predictable! They might end up becoming more "back heavy" like raccoons, or rely on the invention of shoe/gloves, or just abandon silent hunting all together to become tool-reliant.)

Paw Pad Changes

Cats use the pads on their paws to move silently. As long as the species is relying on silently stalking prey, they will need to have these pads in contact with the ground to be good hunters.

So instead of the digital pads sliding down to create the "top" of the palm, I figured the metacarpal pad would split in two. So now there's a snug, dipped "shape" with which they could nestle an object into as they work with it, but also there is ALWAYS still pad in contact with the ground.

The amount of fur in-between the bottom (metacarpal) and top (supercarpal) pads probably just depends on culture and genetics. It wouldn't really have enough of an impact on the paw to be selected for to be furry or hairless.

I can imagine some groups being weird about it and thinking it should be shaved or braided or something, lmao. Or cats who live in muddy environments clipping it for hygiene reasons.
