A little perspective
Cat vs Human femur: length comparison
The body length of a cat is about 1.02 times the adult bone length of the human femur.
A cat is a small domesticated mammal with a flexible body, retractable claws and highly developed senses.
The human femur is the thigh bone, connecting the hip to the knee and supporting body weight during movement.
Both rulers start at the same zero and share one linear scale. Artwork keeps its original proportions. Horizontal rulers compare the selected spans; vertical brackets also identify height on the artwork.

Cat
Body length: 46 cm; example.
Defined example; real examples vary. The 4 kg mass is an explicit assumption, not a species average or product specification.
Nose-to-rump reference span; tail excluded. Poses and unmeasured details remain representative.
Defined examples — our methodology
The marked body length is calibrated. Unmeasured illustration details are representative.
Human femur
Defined adult bone length: 45 cm; defined specimen; range 40 cm–50 cm.
A defined adult human femur 45 cm long and about 300 g as a dry bone. Length, mass and morphology vary with the person; no clinical inference is intended.
Encyclopaedia Britannica — Femur

Why this measurement?
Why we use 46 cm
We compare the body length of a cat. This is an illustrative comparison value, not a claim that every example is the same.
