Rat Species in Vancouver:

The two most common rat species in Vancouver are the Norway rat (Rattus norvegicus) and the roof rat (Rattus rattus). Both are highly adapted to urban environments, thriving near humans due to their scavenging behaviors. 

Breeding Habits:

Rats are prolific breeders, with females capable of producing up to 12 litters per year. The gestation period is approximately 21 days, and each litter contains 6 to 12 pups. This rapid reproduction allows rat populations to expand quickly in favorable conditions. 

Feeding Habits:

Rats are opportunistic feeders, consuming grains, fruits, vegetables, and even meat. In urban areas, they are attracted to food waste from garbage bins and improperly stored food, making human habitation a key feeding ground. 

Morphology:

Norway rats are larger and stockier, with a blunt nose and a thick, scaly tail. Roof rats are sleeker, with a pointed snout and a tail longer than their body. Both species have highly developed senses of hearing, smell, and touch, aiding their survival. 

Lifestyle:

Rats are primarily nocturnal, preferring to forage and explore in the dark. They are excellent climbers, often found in elevated areas like attics, rooftops, and trees. Their adaptability allows them to thrive in various environments.
