- Avoid translating as 'рисовая крыса' unless in a strict scientific context; it is a specific zoological term, not a descriptive phrase for a rat that eats rice.
Common Mistakes
- Using it as a general term for any rat near rice; confusing it with other rodent species like the common brown rat.

FAQ
Frequently Asked Questions
No, it is a specific taxonomic grouping of rodents within the family Cricetidae, not merely a descriptive term.
They are not typically aggressive but can be agricultural pests and, like many rodents, may carry diseases.
It is highly specialised terminology and would sound odd in general conversation outside specific contexts.
They belong to different biological families; rice rats (Cricetidae) are typically New World species with different morphological and ecological traits from the common brown rat (Rattus norvegicus) which is in the family Muridae.
