Why are cats so slinky?

Why do cats scratch?
Scratching on something isn’t just a grooming behavior that keeps the claws under control. It’s also behavior that helps mark a cat’s territory with the physical signs and also the scent of its paws. When a cat scratches on something, that’s telling other cats (which may or may not be in the house – this is pure instinct) that the area belongs to the cat. With multiple cats, they may reinforce the marking and all scratch on the same area, or if there are territorial issues, they may not feel safe to scratch in an area (like a scratchpost) if it’s been ‘claimed’ by another cat. (If you have issues with litterbox training, make sure that a dominant cat isn’t guarding the litter box. You may need more than one litterbox if this is the case.)

Actually cats get more serious injuries than many think. True, the cat tends to land on four legs, and also true that during a fall the Righting Reflex kicks in with the tail acting as a rudder, their bodies twisting to put them in an upright position and the muscles of the body tightening and the cat’s body sort of splaying out to create drag and a declerating effect, but many cats still get serious injuries if they survive . How do cats survive falls from great heights?

Cats have floating shoulders, no clavicles. The muscles are attached to the sternum and the scapulae.

Brittanica.com says they dont exist..... but the illustration above has a clearly labeled clavacle.

Huh. I guess they're vestigial. I don't quite know what to do with them other than wire them so they're floating, then ._.

Of course cats have clavicles! ALL cats do! I published the first paper on the clavicle of Smilodon and in it we analyzed the clavicles of all cat species.

I agree on leaving repairs as being obvious. As long as the outline is correct and it's off just enough so it does not detract from the actual skeleton itself.
