What each measurement buys
Crate
crate_length ≥ body_length + margin(2–4 in); crate_height ≥ standing height to top of head + a few in. Pick the smallest standard crate whose length ≥ that. Bigger is NOT better for crate training (too much room defeats den security); size to the dog, not to spare.
Recommended: 22″. Measure your dog nose-to-tail-base and standing height, add the margin, and confirm against the crate's INTERIOR (not exterior) dimensions before ordering.
Harness
chest_girth + two-finger ease → choose the harness size whose girth range covers that number.
Your Cat — Medium (≈8–12 lb)'s typical chest girth is 12–17 in; match a harness whose girth range covers your measured number plus two fingers.
Collar
neck_girth + two-finger ease → collar's adjustable range should sit mid-range at that number.
Typical neck 7–10 in. Cats MUST use a breakaway/safety collar — hard requirement, not a preference.
