Mouse · 0 live listings

The standard fancy mouse is the domestic house mouse with a short, smooth coat, bred in hundreds of colors and markings. It is small, quick and entertaining to watch, and it suits owners who want a lively cage more than a lap pet.

Scales follow breed-club and veterinary consensus; individual animals vary. Listings show what each seller has on file.

The tradeoffs, honestly

Mice live about two years, move fast and are more for watching than cuddling. Bucks smell strongly and usually must live alone.

Common questions

Should I get does or bucks?

Does usually live happily in groups of two or more. Bucks tend to fight once mature, so most live alone, and their urine smells much stronger. For a first cage, a trio of does raised together is the easiest start.

What health checks should I ask about?

Mice live only about two years, so ask for a birth date and a litter record. Ask about tumours and respiratory trouble in the line, check for clear eyes, a clean coat and no scratching, and ask for vet-confirmed sex: most pet mice are sexed wrongly at least once.

What cage does a mouse need?

A tank or bin cage with bar spacing no wider than about a quarter inch, deep bedding for burrowing, a solid 8-inch wheel and plenty of hides and climbing.
