Rats are found mostly in our urban areas of Connecticut.
Currently the only rat that we have in Connecticut is the Norway Rat aka the sewer rat. The only other rat in North America is the Roof Rat which we don’t have a problem with…yet. Roof rats are found more down south. Norway rats are grayish-brownish in color. They also can vary from white bellies to brown or even brownish-red fur. Because of the variation in color, this should not be the only method for identifying a rat. They weight in at about 12-16 ounces and can measure up to 16 inches from nose to tail tip. There are some reports of larger rats, but “rats the size or cats” do not exist. What these people are seeing are most likely juvenile opossums being mistaken for a rat. Rats will breed pretty much all year round, provided the conditions are favorable. The female rat’s gestation period is about 22 days and will give birth to 8-9 pups, sometimes more. The pups will reach sexual maturity in 12 weeks and begin breeding just as soon. Rats can live up to 3 years in captivity (pets) but in the wild 12 months is the average life span.
