What is the Ferret Breed Identifier?
The Ferret Breed Identifier estimates the likely breed mix of ferrets from physical traits or photo cues. Knowing what you're working with shapes everything from diet and housing to expected size and temperament. That is useful for new owners and shelters alike.
A well-cared-for ferret usually lives somewhere between 6 and 10 years. They are an obligate carnivore, so their nutritional needs shift with age, size and activity. Ferrets need a tall multi-level cage for sleeping plus several hours a day of supervised, thoroughly ferret-proofed roaming, since they squeeze into any gap and chew soft rubber. The usual suspects for this species are adrenal disease, insulinoma, lymphoma, so any noticeable change is worth following up.

How does the Ferret Breed Identifier work?
The result is based on matching the traits you describe against commonly documented characteristics for ferrets, not genetic testing. Use it to know roughly where you stand and what to ask about, not to rule anything in or out on its own.
What affects the result
- Physical traits such as size: coloring and markings
- Behavioral traits: which can be just as informative as appearance for some questions
- Age: since juvenile traits can differ noticeably from adult ones
- Photo or description quality: the more specific your input, the more useful the match
How do you use the Ferret Breed Identifier?
- Pick your adult size (Very small, Small, Medium, ...)
- Pick your coat length (Hairless or very short, Short and dense, Medium, ...)
- Pick your ear carriage (Erect, Folded or dropped, Semi-erect, ...)
- Pick your overall build (Slender and fine-boned, Balanced, Stocky and heavy-boned)
- Pick your dominant color pattern (Solid single color, Two-tone or bicolour, Brindle, merle, tabby or ticked, ...)
- Press Calculate, then read the result alongside the sources listed below
Worth doing: jot down the date and the result each time. A single number tells you little, but a trend across a few months tells you a lot about your ferret.

Before you rely on this
Averages hide a lot of variation. The figure here reflects what is typical for ferrets, but your ferret may sit well outside it for perfectly ordinary reasons. Use the result to spot changes over time in your own animal rather than to compare it against other people's pets.
