Rodents

The 'small pets' — hamsters, gerbils, rats, mice, guinea pigs, chinchillas, and their honorary neighbors the rabbits and ferrets — pack complete personalities into starter-pet packaging, but their needs are anything but miniature. The tiny cages sold next to them in pet shops are almost universally too small: modern welfare standards call for enclosures measured in square meters of floor space and depth of digging substrate, not liters. Two rules sort this whole category. First, teeth: every rodent and rabbit has continuously growing teeth, so unlimited chewing material (and for rabbits and guinea pigs, unlimited grass hay) is medical care, not a toy. Second, social wiring is species-specific and absolute — Syrian hamsters will fight to the death while guinea pigs, rats and gerbils sicken in solitude. Match the species to your household honestly: nocturnal watchers (hamsters), interactive extroverts (rats, rabbits), or chatty daytime herds (guinea pigs).
