Water Rat and Otter: Differences
The water rat, commonly referred to as the marsh rat or by its scientific name Nectomys , belongs to the family Cricetidae. It is a semi‑aquatic rodent native to tropical and subtropical regions of Central and South America. Morphologically, the species exhibits a streamlined body, dense waterproof fur, partially webbed hind feet, and a flattened tail that functions as a rudder during swimming.. Date latest changes:
What Can and Cannot Be Given to Rats as Food
Rats require a diet containing approximately 14–20 % crude protein on a dry‑matter basis to support growth, reproduction, and maintenance. Protein quality matters; amino acid profiles should meet the rat’s needs for lysine, methionine, and tryptophan.. Date latest changes:

Why Cats Bring Mice into the House: Causes and Significance
Domestic cats retain hunting instincts forged in the wild, where capturing small vertebrates ensured survival.

Rat Biting Fingers: Causes and Prevention of Nipping Habits
Rats may nip for two distinct reasons. Playful nips occur during exploration or social interaction; they are brief, gentle, and often accompanied by relaxed body posture, upright ears, and soft vocalizations.

Do Rats Transmit Rabies to Humans? Risks and Prevention
Rabies is an acute, neurotropic viral disease caused by members of the Lyssavirus genus. The virus infects mammals through saliva, typically introduced by a bite or scratch from an infected animal. Once inside the host, the pathogen travels from peripheral nerves to the central nervous system, where it replicates and induces progressive encephalitis.. Date latest changes:
How to Help a Rat Sleep: Calming Techniques
Rats are polyphasic sleepers, dividing rest into multiple periods throughout a 24‑hour cycle. Adult laboratory and pet rats average 12–14 hours of sleep each day, with night‑time accounting for the majority of that total. Sleep occurs in short bouts lasting 5–15 minutes, interspersed with brief awakenings.. Date latest changes:
