Young lender voles in their nest beneath a Wooden pile Rodents may be born possibly altricial (blind, hairless and comparatively underdeveloped) or precocial (mainly furred, eyes open up and reasonably made) with regards to the species. The altricial state is common for squirrels and mice, while the precocial point out typically takes place in species like guinea pigs and porcupines. Females with altricial youthful generally Create elaborate nests ahead of they offer birth and retain them till their offspring are weaned.

[75] Rats also require loads of space and could become very tame, can master tricks and manage to enjoy human companionship. Mice are brief-lived but just take up hardly any space.

In the case of marmots, resident males don't appear to at any time reduce their territories and normally acquire encounters with invading males. Some species can also be known to immediately defend their resident females and the following fights can cause critical wounding.

Laboratory (brown) rats might hold the potential for metacognition—to take into consideration their very own Mastering and after that make conclusions dependant on the things they know, or do not know, as indicated by options they make evidently trading off problems of tasks and predicted benefits, producing them the first animals aside from primates known to get this ability,[eighty][eighty one] but these results are disputed, For the reason that rats could have already been following simple operant conditioning rules,[eighty two] or simply a behavioral economic product.
