Husbandry
Husbandry blocks cover housing, environment, and daily-care essentials. Presented verbatim. (2 blocks.)
Husbandry of pet rats and mice (caging, solid floors, bedding, ammonia control)
The best cages for pet mice and rats are made of a material that is easy to clean and deodorize and that is indestructible to rodent chewing or digging in the corners. The cage floor can be solid but should be waterproof and easy to clean. Wire-mesh floors should be avoided because rats and mice can trap their feet, and especially hindlimbs, in the openings, resulting in fractures and injuries.
Appropriate husbandry is key to maintaining the health of pet mice and rats. Use of appropriate bedding and frequent cleaning of cages help prevent respiratory diseases that can be exacerbated in an environment with increased ammonia levels.

Health & Disease
Health blocks cover common conditions and their clinical signs, drawn from professional veterinary references. Presented verbatim. (3 blocks.)
Dental disease in pet rats and mice (continually erupting incisors; overgrown incisors most common)
Dental problems are common in pet mice and rats because of their continually erupting incisors. Overgrown incisors are the most common problem in rats and mice (in contrast with cheek teeth malocclusion, which is the most common problem in guinea pigs and chinchillas ).
