Four tools · No paywall · No named reviewer

Four tools. The numbers are the ones on their own pages.

Age prints an editorial estimate. Hutch size checks the housing minimum already in use on this site. Cost totals and breed names stay blank until a source is on file.

Data files checked 2026-10-21

No board credential and no annual audit are named on this page. The formulas below are the ones the live tools already run.

Tools, not a clinic

What these tools will say

A number needs a rule this site can show.

Two of the four tools answer with a figure: the age estimate, and a pass or fail against the housing minimum. The cost tool and the breed quiz stop when the data file is empty.

  • Age ×21, then +6
  • 3 m × 2 m × 1 m

Live tool 01

Rabbit age estimate

Editorial estimate

The first rabbit year is multiplied by 21. Each later year adds 6. Body size does not change the result. The labels Baby, Adolescent, Adult, Mature, and Senior belong to this calculator.

Worked example · 4 rabbit years

39 human years, labeled Mature

Indoor lifespan on file is 8–12 years, from the House Rabbit Society page the age tool cites. A care protocol is not attached to this number.

Quick age estimate

A labeled estimate, not a veterinary conversion.

Live tool 02

Cost calculator

No prices on file

The calculator can count rabbits and pick housing, a vet plan, and a region factor. It still prints no dollar total. The price list has 0 lines. A downloadable audit is not a file on this site.

First year No total Setup plus one ongoing year
Monthly No total Needs a sourced price
Lifetime No total Setup plus 10 ongoing years

Region factors on file are ×0.85, ×1, and ×1.25. They are an editorial scale, and they do not create a price. The 10-year span is the midpoint of the indoor 8–12 range.

The other two, and two that are not tools

Space, plants, portions, breeds

Enclosure size and the breed quiz are live. A forage database and a portion scale are not.

Live tool

Enclosure size

Compares a pen with 3 m × 2 m × 1 m. A square-foot slogan is not the figure this check uses.

Minimum floor 3 m × 2 m

Height 1 m. One block, all the time. Upper floors do not count.

Greens and forage

A plant search that grades leaves as safe or toxic is not on this site. The greens guide is a title, and it is not written.

Safe greens is listed, not written
8 questions

Breed quiz

Eight questions about the home. The result does not name a breed. A count of varieties is not printed.

Age estimate

At or under 1 rabbit year, human years = age × 21. After that, human years = 21 + (age − 1) × 6. Written through 12 rabbit years. The note in the data file says this is not a published biological formula.

Housing minimum

RWAF Space Recommendations and the RSPCA page in the same file: at least 3 m × 2 m × 1 m. Fetched 2026-10-21.

Cost arithmetic

When a price line has a source, lifetime is the one-time setup plus the ongoing year times 10. The first year is not added a second time. Today the line list is empty, so the screen stays blank.

Lifespan source: How Long Do Rabbits Live? — House Rabbit Society, fetched 2026-10-21. Indoor 8–12 years. Outdoor domestic about 3–5 years is on that page and is not the calculator’s range.
