Rex

Mouse · 0 live listings

Rex mice carry a dominant gene that makes the coat and whiskers curly. Care is the same as any fancy mouse, though the coat is usually tightest in young mice and can relax or thin as they mature.

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

The tradeoffs, honestly

The curly coat often loosens with age, so a tightly curled baby may not stay that way. Short lifespan and the buck smell are the same as any mouse.

Common questions

How is rex different from frizzie?

Both curl the coat, but rex is dominant, so one copy shows, while frizzie is recessive and needs two. Ask the breeder which gene the line carries if you plan to breed.

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.

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.
